After ONLY ever owning HK centre-fire semi-auto pistols, I finally purchased my first 1911: an STI Ranger II 9mm.
I put 200 rounds through it last night, and I was VERY impressed with the accuracy. I shot more accurately with this gun than with any HK I've owned (and I've owned them all). However, I was not impressed with the reliability. I had about 5 misfeeds in the 200 rounds. 4 happened with one of the mags and 1 happened with the other mag. Essentially, the bullet was jamming up on the feed ramp and in a couple of cases the entire round stovepiped. Also there was one instance where the hammer did not #### after the shot (i.e. the slide did not retract far enough, after the shot, to #### the hammer).
I was shooting 147 grain, FMJ, winchester white box. Are these sorts of failures common with the 1911 platform? Perhaps the squared-off bullets of the 147 grain round aren't ideal for the 1911? Or, perhaps the higher velocity, higher energy of the 115 grain round would cycle the slide better, thereby increasing reliability? Any advice appreciated.
