Hello guys, I'm new to this forum, just wanted to share my experiences and talk to other knowledgable CZ luvers. I've owned a P01 in the past. The gun was awesome, ran great, never had any issues. The thing ate everything I fed it. My wife luved it but wanted it in a smaller package. That drove me to find a Rami BD 9mm. Picked one up used thru ppt transfer (non-roster gun in Cali). Got it home and put the trigger pull gauge on it. DA read around 9.5 lbs and SA around 5lbs. So just like I did for the p01, I ordered the CGW ultralite kit for it. After installation, proper cleaning/lubrication how I like, the numbers read DA 6lbs 13ozs SA 3lbs 14ozs (installed the blue hammer spring). The little gun ran awesome at the range no problems. Very accurate gun for such a short sight radius. Well....today decided to experiment even further. The kit came with a 11.5# hammer spring recommended only for Federal&Winchester primers. Plugged that one in, now she breaks at DA 6lbs flat SA 3lbs 9ozs. I'll let you guys know how reliable it runs after some range time.
