I just got home from my second day in a row shooting my 12 year old P-09 at 200 yards and can't imagine trying to run a stock CZ again. I put a video up in the Day at the Range section. I won't buy a later one myself, but, if I ever did, it would get the CGW kit before ever going to the range.
And I did shoot two sub 8" seven shot groups at 200 yards yesterday. Today was gusty windy, so I am still analyzing my results. I might put another video up tomorrow, if today's results aren't too embarrassing, LOL.
