put 250 rounds of CCI Blazer through my Razorback today. Had only 2 malfunctions but both I beleive were due to bad primers in the ammo. Put 50 rounds of (forgot) hollow point ammo. Did have to push the slide forward once when one of the hollow points got hung up on the feed ramp. So in 300 rounds it really did function well. I was not all that accurate with the gun. I don't know if I ever got the adjustable sights set up right or not. I have never really shot a gun much that has adjustable sights. After 10 yards my groups were not very good. I will put a few hundered more rounds through it in the morning.
