I have not had mine very long. Bought it used so don't know how many rounds have been through it. Very dirty when I got it, but it cleaned up nicely. In short, I really like it. I have had it out three times and a buddy of mine once. Probably 200 total rounds. It is very accurate and there has not been a malfunction of any kind since I got it. I have it with me just about every day. Swap it out with my CW9 that I have had longer. Both are really accurate, at least out to 7 yards, with the CW45 having a slight edge. Easy to take down and re-assemble, also. Don't know how it is going to hold up long term, but it's great so far. The only draw back so far is the cost of extra mags. and the CW series only come with one.
