For example, MAB model Ds (like Unique, in 1939 all MAB production was diverted to producing the MAB model D for the French military) used by the French army can only be identified by whether their serial numbers fall in a certain range. Model B Type I. The first MAB Model B was assembled on 8 August 1932-it had a nickel finish and its serial number was 79084. Obviously, MAB did not start a new numbering series for the new gun, so I assume that the Model B was numbered in the same series as the Model A.

The M.A.B. Model R
by Ed Buffaloe
After World War II the Manufacture d’Armes de Bayonne was faced with rebuilding its business. The factory had been taken over by the Germans in late June 1940, and Bayonne was not liberated until 24 August 1944. The company was able to restart production of most of its models in 1946, under the leadership of Jean Barthe (pronounced “Bart”), the son of the founder, Léon Barthe. Over the next several years under Jean Barthe’s direction, production of most models was simplified wherever possible in order to reduce manufacturing time and cost. In 1949 the Model B was dropped completely.
The MAB model R was a new departure for the company. According to Bastié and Casanova, who have done more research than anyone else on MAB pistols, it was intended as a replacement for the Model D, the 7.65mm version being identical in size to the Model D. Like the Model D, the Model R in calibers larger than .22 utilizes a concentric recoil spring and an unlocked breech mechanism. The Models D and R differ in that the Model R has an external hammer, no grip safety, and a mechanism to lock the slide open after the last round is fired. Additionally, when a fresh magazine is inserted into the Model R the slide automatically closes, chambering the first round. The external hammer has a half-cock position, which serves as an additional safety feature. The manual safety locks the connector bar, but does not directly block the sear.
In the four years between 1950 and 1954, four different Model R pistols appeared. These are:
The Model R in 7.65mm French Long caliber (R-32L).
The Model R in 7.65mm Browning (.32 ACP) and 9mm Browning Short (.380 ACP) calibers (R-32 and R-380).
The Model R in 9mm Parabellum (R-9).
The Model R in .22 Short and .22 Long Rifle (R-22).
All these different designs were referred to by the MAB company as the Model R. I have given them individual designations for convenience in order to write about them with greater clarity. I should point out that Huon does not list the 9mm Browning Short (.380) version of the Model R, but it is listed by both Josserand and by Bastié and Casanova, and in the manual provided by MAB. However, I have been unable to locate a photograph of a Model R in 9mm Browning Short.

The Model R in 7.65mm French Long (R-32L)
MAB Model R in 7.65mm French Long
The French war in Indochina begain in 1946 and didn’t end until 1954. At the beginning of the war the French service pistol was the Model 1935A or 1935S, which shot the 7.65mm French Long cartridge, so it only made sense for MAB to consider chambering its new Model R in the same cartridge. Unfortunately, the French military had already decided to switch to the 9mm Parabellum for their military handgun, but MAB apparently did not know this, and in any case the military’s decision on a new design was not finalized until late in 1951 (the MAC 50 was chosen).
According to Huon, the first Model R-32L was manufactured on 23 July 1950. He believes that almost all of these guns were shipped to Indochina, and that less than 1000 were made because he has never seen one with a serial number larger than three digits. At this time we have no other evidence as to how many were actually made. The serial number tested by Huon was 702. These guns were not exported to the U.S. and are almost never seen here.
The Model R-32L is slightly longer than the Model D, due to its extended grip tang and the slightly deeper grip necessary to accommodate the longer cartridge. It has an external hammer with a round head with a hole drilled through it. Like the Model D, the magazine release and manual safety lever are both on the left side where they are easily accessible to the thumb of a right -handed shooter. There is an external slide release inconveniently located on the right side of the gun. The lever pivots just behind the pivot point of the trigger, and extends backward under the top portion of the right grip plate, which is split to allow the checkered button to be pressed downward. However, a slide release is only occasionally necessary since the gun automatically frees the slide when a new magazine is inserted. There is a lanyard ring on the bottom of the grip. Like the Model D and the 1910 FN Browning, the barrel is retained by three transverse lugs just beneath the chamber which fit into grooves in the top of the frame. There is no magazine safety on the R-32L.
The gun is marked on the left side of the slide in all capital sans-serif characters (except for the ‘R’, which has serifs):
PISTOLET AUTOMATIQUEMABBREVETE MODELER
and on the right side of the slide:
MADE IN FRANCE
The serial number is on the right side of the frame, just above the trigger, and again just beneath the bottom grip screw under the grip plate. Visible in the ejection port, the barrel is marked MAB Cal. 7,65. There is nothing to indicate that the gun is chambered for the French Long cartridge rather than the Browning cartridge. Huon states that the grip panels are of black plastic with the MAB monogram, and that on the gun he tested the grip plates were badly aged and slightly uneven. The only R-32L I have a photograph of shows the right grip plate broken, with only a small portion remaining at the top.
Field Stripping the R-32L
Make sure the gun is unloaded.
Remove the magazine.
Press in and turn the barrel bushing 1/4 turn and ease the bushing forward (be careful, as it is spring loaded). Remove the bushing and recoil spring.
Draw the slide back and allow the slide lock to engage.
Turn the barrel counterclockwise, rotating the barrel lugs up into the slot cut in the interior of the slide.
Release the slide by pressing the slide release on the right side, above the grip.
Draw the slide and barrel off the front of the gun.
Rotate the barrel and remove it through the front of the slide.
The Model R in 7.65mm Browning and 9mm Browning Short (R-32 and R-380)
MAB Model R in 7.65mm Browning
The Model R was introduced in 9mm Browning Short (.380 ACP) on 26 December 1950, and in 7.65mm Browning (.32 ACP) on 1 February 1951. The R-32 and R -380 are eight millimeters shorter than the R-32L, having a narrower grip and a barrel that is 5mm shorter. Early illustrations show these guns with a round head on the hammer like the R-32L, but the few examples I have encountered have a spur hammer. The other differences are that MAB added a magazine safety and eliminated the slide release button on the right side, which wasn’t really necessary anyway. The slide locking mechanism was moved further to the rear so that it is covered by the right grip plate. Very few guns in either caliber were ever made-- possibly only a few hundred of each caliber, possibly less. A few were imported into the United States by the Western Arms Corporation (later known as Winfield Arms Corporation) and are usually found marked “Made in France for W.A.C.” Bastié and Casanova state that these guns came into direct competition with the already well-established Model D and never found a market of their own.
Markings are identical to the R-32L, except the ‘R’ is sans-serif:
PISTOLET AUTOMATIQUEMABBREVETE MODELER
The barrel of the R-32 is marked MAB Cal. 7,65. I have been unable to locate an R-380 to know how it is marked. An early manual illustration for the R-32 and R-380 shows the gun with a round-head hammer like the R-32L, but I do not know if they were ever actually manufactured in this configuration. Early advertisements also show the round-head hammer.

Make certain the gun is unloaded by drawing the slide back and checking the chamber. If the slide locks open, close it by inserting the magazine.
Press in and turn the barrel bushing 1/4 turn and ease the bushing forward (be careful, as it is spring loaded). Remove the bushing and recoil spring.
Draw the slide back until it locks open. Remove the magazine.
Turn the barrel counterclockwise, rotating the barrel lugs up into the slot cut in the interior of the slide.
Release the slide by inserting the magazine, then remove the magazine again.
Draw the slide and barrel off the front of the gun.
Rotate the barrel and remove it through the front of the slide.
Note: If you remove the grips, be sure to observe that the lower screw is longer than the upper screw, and they must not be reversed.
The Model R in 9mm Parabellum (R-9, sometimes referred to as the R Para)
MAB Model R in 9mm Parabellum
The R-9 was first manufactured in October 1951. The R-9 is larger and heavier than the previous guns, and the barrel of the R-9 is retained by a transverse pin instead of by lugs. In addition, the R-9 features a buffer spring with a similar function to that in the 1908 Bayard. This is a small spring in the frame directly behind the barrel step which pushes the barrel forward against the retaining pin. During recoil, the barrel is able to move with the slide against this spring for a few millimeters before it is stopped by the frame and the slide continues rearward by itself. The barrel is prevented from moving forward by the transverse pin, which must be removed to disassemble the gun. The R-9 incorporates a magazine safety which not only prevents the gun from firing with the magazine removed but also prevents the gun from being cocked.
The R-9 was imported into the United States by Western Arms Corporation and is usually marked “Made in France for W.A.C.” According to Bastié and Casanova there was little consumer interest in the R- 9 and most were sold in the U.S. where the gun was eventually branded by Winfield Arms as “Le Militaire”. The highest serial number I have documented for an R-9 is 1422.* According to Huon, production ended in November of 1963 when design work began on what was to become the P-8 pistol.
Slide markings are identical to the R-32 and the R-380. There is no indication of caliber on the barrel. Grips are of cheap plastic that shrinks and cracks easily, and usually have the MAB monogram in an oval, though U.S. imports usually have WAC in an oval instead.
Field Stripping the R-9:
MAB R-9 Field Stripped
Clear the breech, close the slide (by reinserting an empty magazine), then remove the magazine.
Twist the barrel bushing approximately 1/4 turn counterclockwise (as you face the front of the gun) and ease it off the front of the gun. Be careful! The spring is quite stiff and powerful.
Remove the recoil spring and barrel bushing.
Move the slide backward on the frame about 1/4 inch until the takedown notch on the right side of the gun lines up with the retaining pin.
Push the pin in on the left side of the gun and pull it out the right side.
Remove the barrel and slide from the frame.
The barrel will lift out of the slide.
Note: As on earlier M.A.B. pistols, the grip screws come in two lengths--the shorter screw goes on top. During reassembly, you must push the barrel back against the spring in the frame in order to insert the retaining pin.
At the range, the R-9 exhibited the same stiff trigger I have found on earlier MAB’s--it has almost identical lockwork. By concentrating, I was able to put a few rounds from each magazine in the bullseye at 30 feet, but inevitably the rest were flyers. The barrel is very closely fitted in the slide, so I think the gun has the potential to be quite accurate, but is limited by its less-than- optimal trigger. The recoil was not unreasonable--certainly less than a .357. The first time I inserted a loaded magazine, the slide did not close--I simply pulled back and released the slide and it chambered the first round. Subsequently the breech closed automatically each time I inserted a magazine. When I cleaned the gun, I discovered that the screw holding the slide lock mechanism was a bit loose, so I tightened it. The R-9 fed and ejected standard hardball 9mm ammunition with no problems.
Ergonomically, I find that the R-9 fits my hand well, but my thumb is not quite able to reach the safety lever without me shifting my grip position. And I find the slide lock mechanism is not well thought out. If you draw the slide back to check for a round in the chamber, or for any other reason, and the magazine is empty, the lock mechanism will engage and you have to remove and reinsert the magazine to get it to close. It would have been better if they had retained the manual release of the R-32L. Even on the right side it would be better than not having one.
The Model R in .22 Caliber (R-22)
MAB Model R in .22 L.R.
This is a completely different gun from the earlier Model R pistols, and probably should have received a different model designation. The slide inscription does not include the Model R designation, but the grip plates are marked with an ‘R.’ The only feature it has in common with the other Model R pistols is its external hammer. It differs from the earlier guns in that it has a fixed barrel, an open-top slide, does not lock open after the last round is fired, and does not have a half-cock position for the hammer. It is somewhat like the MAB Model F, but has an external hammer instead of an internal striker, and a less-radical grip angle. The R-22 bears a striking resemblance to the Star Model F.
The R-22 in caliber .22 Short, with a 185mm barrel, was first manufactured on 26 July 1954. This gun was specifically intended for olympic competition. The manual for the gun refers to it as “Pistolet Automatique de Tir, Modèle R Olympic.” The Olympic model is identical to later R-22 pistols except for its chamber size.

The left side of the slide of the Olympic is marked in all capital sans-serif characters:
CAL .22 COURT. PISTOLET AUTOMATIQUEMABBREVETE -S.G.D.G.
The right side of the slide is marked MADE IN FRANCE.
According to Huon the .22 Long Rifle version with a 110mm barrel appeared on 5 December 1954. Interestingly, the long rifle version was reviewed in the American Rifleman for January 1955--the month after production began. This short-barrel .22 Long Rifle version is the most common R-22. Again, according to Huon, on 31 January 1955 the 185mm barrel became available chambered for the .22 Long Rifle. Bastié and Casanova state that both of the MAB .22 target pistols (the Model F and the Model R) were reduced to the status of beginner guns by the more critically accurate target pistols made by Unique and Walther. According to Huon, production of the R-22 ended in April of 1965, though sales may have continued from remaining stock for several years.
The left side of the slide is marked in all capital sans-serif characters:

The right side of the slide is marked MADE IN FRANCE.
MAB pistols were imported in the United States during the 1950s by the Western Arms Corporation of Los Angeles, California and sold by its distributor, the Winfield Arms Corporation. Eventually the various guns were given names instead of letter designations, so the R22 became “Le Chasseur,” the hunter. Guns for export to the United States were marked on the left side of the slide:
.22 L.R. “LE CHASSEUR”MADE BY “MAB” IN FRANCE FOR “WAC”
The right side of the slide is unmarked.
Two different front sights were available for the R-22, one with a graduated thumb wheel to raise and lower the sight, and another with a screw. Grip plates appear to be made of plastic, but the plates are thick and both guns I own have grip plates that are in excellent condition--no sign of shrinking or cracking. Grip plates have the MAB monogram in an oval near the bottom and an R in a circle at the top. Most guns came with an extra left side grip plate with an extended thumb rest at the top instead of the R in a circle. The grip plates for guns imported into the U.S. have the word “Winfield” in an oval near the bottom instead of MAB, and at the top is a circle with “.22 LR” in it.
Like all the MABs, the R22 was well made. Though not as highly polished or carefully finished as a Colt or a Smith & Wesson, the MABs were nonetheless manufactured with great precision and careful quality control. My R-22 is extremely reliable and quite accurate. My only complaint about the gun is that, unlike the other R-series guns, there is no provision for locking the slide open when the last round is fired. This means you must count rounds if you do not wish to have the firing pin impact the top of the barrel if it should fall on an empty chamber.
Field Stripping the R-22
MAB R-22 Field Stripped
The R22 has a latch on the left rear of the frame with two holes in it. The latch requires a special tool, which must be inserted into the lower hole, to open. A spring -loaded plunger in the bottom hole holds the latch in place. Field stripping is accomplished as follows:
Pull the slide back about 1.5 cemtimeters and lock it open by moving the safety lever up into the middle detent on the slide.
Insert the take-down tool into the bottom hole in the latch and pull the latch downward. The spring-loaded plunger beneath the latch will catch in the upper hole and hold the latch open.
Pull the safety lever down. Grasp the slide, pull it to the rear, and lift it up out of the rail on the frame.
Carefully ease the slide off the front of the gun.
My R-22 did not come with the take-down tool. I made one from a brass end that came with a gun cleaning kit. The brass piece was for pushing cotton patches through gun barrels, and had a long point on the end. I ground the point down to the correct diameter, ground the length down to the same depth as the latch (about 9/64 inch) and rounded the end with a file. It isn’t perfect but it suffices, and the brass will not scratch the gun.
Production of the large caliber Model R pistols ended in 1963, whereas production of the R-22 ended in 1965.
