This pistol came about for usage by the Mexican military through a presidential decree in 1893 by president Porfirio Diaz.
The pistol was built in Liege, Belgium by the Pieper firm. It uses a gas seal design where the cylinder moves forward to seal it during firing. This is the same concept as the Nagant revolver. It is a seven shot double and single action revolver. The total contract was for 5000 pistols.
Hard rubber plastic grips with H.Pieper Patent markings
The rear of the cylinder showing the rebate area for the rims
The front of the cylinder for the gas seal
Lanyard attached on the pistol grip
Cylinder latch. Looks like a Colt design. EJERCITO MEXICANO stamped on the side of the frame , top strap and cylinder.
Markings on the cylinder







is the trigger pull better than the nagant? gas sealed revolvers are very cool
That one is great I have never seen one before. What caliber is it ? Looks like a 32. I think Mexican made guns are very interesting. Ian could do a piece on this gun Bob.
I have one of these Pipper revolvers in unworking condition. Is it worth trying to salvage?
(Broken grips and internals, the rest is quite fine)
