I fired mine years ago.
Made blackpowder rounds out of .44 special cases cut down, cast a bullet (can't remember the mold I used) as close to proper diameter as I could get using pure lead, then hollowed the base with a drill press to form a skirt that would blow into the rifling.
Accuracy was passable at 10 yards, minute of Chadian Resistance Fighter.
The French were never known for adopting handguns of anything even remotely resembling power. The 11mm, in various loadings, developed between 100 and 200 ft. pounds of energy.
$150 is a great price for one of these guns in decent condition. Years ago I passed on one in ever better condition than mine for $75. Stupid me.
