Bandit...I had the Ruger before the CZ but I may still purchae the Kadet conversion kit in the future. My only "concern" is that it MIGHT looseen up the original slide/frame fit.
Also, so far I have been very happy with it. The only minor gripe that I have is that you can't replace the grip panels. Yes you can put a Hogue Handall on it but then you'll have to remove it again before you can detail strip it.

RAE...I have to confess that even though I clean the Ruger after every 500 rounds or so I did it w/o the detail strip, ie I would clean the barrel from the muzzle side, while being very careful not to damage the crown, etc. Soon though, I will attempt to do it.
BTW, is the firing pin spring replacement a DIY project?
