Here's a few French pistols that aren't often seen. The first is a MAB (Manufacture d'Armes de Bayonne) Model R. That model designation covers several different types of pistols, including an experimental one in 7.65mm Long. This one is a commercial 9mm P. It's a delayed blowback, in fact the delay is a spring loaded plunger in the frame bearing on the barrel. I'm not sure how this delays things. I've shot it but don't think it would stand up to a steady diet of factory 9mm ammo; 9mm +P is out of the question. Now I shoot it with very mild cast bullet handloads, not much more than 380 loads, and it works fine.
The next picture shows two Mle 50s, usually called MAC 50 from the manufacture, Châtellerault. This is still the standard French Army pistol. The Gendarmerie (under the Army) and all armed agencies under the Ministry of the Interior use the SIG P2022. Both of these Mle 50s have Trausch aftermarket grips which are now also installed on all rebuilt pistols. The Trausch grip has the pistol riding a little higher in the hand, preventing hammer bite. The pistols are built like a tank to withstand the very hot French 9mm P ammo which was designed for the MAT SMG. The leather holster is the Mle 48, which can contain anything from a Ruby to a Colt 1911. The web gear is that issued to the airborne, the 'Paras" and isn't very often seen.
