Finally got my M357 A1 last month. In the first 150 rounds I had 8 FTF/FTEs. The spent shell was still snug as a bug in the chamber, merrily blocking the round at the top of the magazine. Needless to say, so far, I wasn't impressed. I've put more than 20K rounds through my Colt Series 80 45 and I've only had one FTF, and that was when I let someone else load my magazine. So, back to Georgia my Steyr went. Well, Steyr made everything ok. The head armorer said that some Steyrs had ejector problems, so they replaced mine under warranty. I say under warrantly, because technically I had voided the warranty by having the slide "Diamondkoted". The armorer felt that the coating process had nothing to do with the problems, so they hooked me up free of charge. I was very impressed by that. So, back to the range. I fired 200+ rounds of Remington UMC and Corbon 125 grain. Occasionally I mixed the two in the same magazine. No problems at all, and the darn thing is far more accurate than I am. These new fangled polymer and steel guns may actually catch on. A question though. There is a space between the magazine and backstrap that is slotted. Is something suppossed to slide into that gap ?
