OK. So here is the report for the 227, only issue I had was a few time the slide would lock back. Tested both mags I have and ran it with Remington umcrap and Winchester service grade 1911 ball (ie, wwb). It ate them no problem just had about 3 or 4 times where it wouldn't lock back the slide. Ergonomically it felt and shot great. By the time I got to doing my grouping tests my hands were pretty worn out by 150 rounds of 45acp and 200 rounds of 9mm. I did notice a few times I pulled low and left but I put that on me as I was going back n forth between 2 triggers systems. A few other guys at the range really liked it as well. This is also the only non glock I've been able to do thumbs forward on with my grip as well. Thumbs up to SIG on that one. Needless to say after this range trip my arthritis is kicked in pretty good and hands are sore till next time. Also the target stand was right in line with the bench stand so I had to stand off to the left of the bench to shoot which is why I think most of them were left of the bull's-eye. I did notice this little gouge on my follower in one of my mags from the edge of the case. Not sure if it's common on SIG 45's. But all in all it shot well with no misfires, ftf, or FTE, just the slide lock back issue. And that could be a number of factors causing that. I didn't get as many rounds for the grouping tests as I did for the glock as I lost track of where I was at on the ammo for the 45 due to having fun and bs'in. All in all its a good gun and I will be having SIG work the trigger over with their action enhancement and srt kit.
