unfortunately, you can no longer buy the ammo that that gun was designed around. the stuff that is available now is the wrong bullet weight and performs horribly.
if you can find the original grain ammo, that thing is a beast.
Favorite range gun for the money - CZ 75B or STI Spartan V 9mm
Go-to carry setup - Walther PPS or PPQ in FIST kydex holster 1AK
Favorite semi-auto design - HK P7
