Some of you may have seen my original thread about the ISSC M22. It is a Glock look alike that shoots 22LR. http://glocktalk.com/forums/showthread.php?t=1151272 I had a horrible time with the original gun, but much to ASA ISSC's credit, they replaced the gun with a brand new one after I had to send my original back to them twice with continuing problems. I don't agree with the way they handle their shipping, as it forces you to go through your FFL. Since you have to go through your FFL, I had to do paperwork for the new gun and that may be a problem for some people. It wasn't a big deal for me because I have a concealed handgun permit, and that allows me to purchase without going through any other processes, but if I didn't have the CHP, I would have had to get a "permit to purchase" from the local sheriff, and that would have cost even more time and money. In either case, I reserve judgement for the new gun until after the "break-in" period. I guess they recommend you break the gun in with 200 CCI mini-mag solid points, but I was only able to find hollow points. Out of the first 100 mini-mag hollow points, I had one failure to feed at the fifth round, which is exactly why I had to send the original back. The rest of the 100 round pack functioned perfectly after that round. Since things appeared to be going so well, I decided to try some Winchester bulk 333 and Federal 550 Bulk and I had several failures of the slide to completely cycle. In some cases, the spent case would be ejected but the next round would not be picked up by the slide. In other cases, the case wasn't even ejected. I attribute this to the ammo being too low powered and the gun still needing break in. I next tried some velocitors and was extremely surprised to find the gun to have several failures with it. I had many, many failures to feed, with the round jamming into the top of the chamber opening. I have come to call this a fish mouth failure, as the soft lead is left with a small outline of the chamber opening curvature and it looks like a little minnow. This was one type of failure I was experiencing quite frequently with the original gun that I sent back. I then switched back to the second 100 pack of mini-mag hollow points, and at first I thought I was going to have many more problems as they also began to fishmouth. But then that went away and I finished out that 100 pack with no problems. I am still going to see about tracking down some mini-mag solid points, and basically run at least 100 of those through it before I consider it broken in. We will see what the gun does after that. I look forward to saying good things about it, considering the company sent me a new replacement gun.
