I've probably only put a couple hundred rounds thru it and all but half a box was Tulammo. It has ran that stuff flawless. I had a half a box of PMC brass ball ammo that it would stovepipe every other round with that stuff. Not sure what the difference was but Im positive it was the ammo and not the gun.
Here is my Glock. Yeah, I know, it's a S&W. But, it shares A LOT of Glock parts, looks similar to a Glock, and Glock makes royalties off of each one S&W sells as part of the lawsuit Glock won against S&W for copying their design.
Oh, and mine cost an average of $275-$300 less than a Glock!
