After 500 rds of 115gr fmj I did not have any malfuctions, so it fit my cw9 very well. I am satisfied with buying the cw9 than upgrading to the new barrel instead of just buying a p9. I give it a 9.9 out of 10 because i have sore thumbs after loading the magazines so many times. lol!!!
You do know that you aren't supposed to shoot cast lead bullets out of a poly barrel. That's the only draw back.
Never trust anyone who doesn't trust you to own a gun.
