I shopped for some time for a used Bersa but found most people want more than new price for a used gun so I just bought new. I did not get whatever "extra" coverage is offered with Gander Mountain to cover warranty shipping, etc. I figure I better go fire the thing and make sure all is good before I take it apart and rework the trigger and such. Is there any ammo that will not fire reliably in this gun? It is the 380.
