I just purchased my M11-A1 on Monday and took it to the range today. I put 150 rds of 115g FMJ and 25 rds of Hornady Critical Duty after the FMJ. I practice the DA and the SA and some DA/SA follow ups. I had 1 stove pipe but was able to clear it no problem. I did notice that the slide would not stay open on several instances. I have read that a lot of people hit the slide stop causes the slide to close after the last shot. When I focused on a "lower" thumb, the slide did lock back. So, I am not sure if i was causing it or if the slide rode forward. The gun is very accurate, but I could tell, I need more work on the DA trigger pull. I found myself pulling low left unless I was really concentrating on the trigger pull. Recoil was real soft even with the Hornady CDuty. Single action pull was superb. All and all, I need more trigger time before i can make it my EDC, but it shot well. Any advise on the slide not staying back on the last shot, I would appreciate it.
