Hi folks, I have ~2,000 rounds through my CZ SP01 Shadow, and just recently noticed a trigger problem. I had just mounted a laser sight on my Shadow and was working on very slow and smooth single action trigger pulls - my focus was not to have the laser dot move on the target. I started to notice that if I pulled too slowly, the hammer would release, but into double action mode. If I released the trigger, the hammer would follow it down to the half #### position. I could continue to pull the trigger in double action mode and the hammer would drop fine.
My Shadow is all stock, still using all the springs it came with. I have field stripped and cleaned after each range trip, but have never done a detail strip to clean the trigger parts. The only modifications I have ever done were replacing front and rear sights.
Have attached a quick video of the problem. You can see single action and double action works fine if I do a quick trigger pull. If I do a very slow trigger pull, the problem starts.
Has anyone encountered this problem before and if yes, how did you fix it? I've done trigger jobs on my Ruger 22/45's, Glocks and 1911's, but never done any trigger work on a CZ yet. Would it be drop in parts like for the 22/45 and Glocks or does it require more fitting/tuning like the 1911 trigger?
