I got the CZC short disco installed in my Shadow 2 along with a CZC Competition hammer, and a 85 C Trigger. No fitting, just drop in parts. I have shot around 1.4K rds through it. Every once in a while I am experiencing a problem decocking the gun and have to apply some force to the hammer to move it. One time I was not able to decock it at all for a while - see the video. After multiple attempts, all the sudden it started working again flawlessly. .
I am thinking that the disconnector may need some fitting. I have also heard that it could caused by the CGW trigger pin. Those pins presumably have some tolerance issues which could account for the intermittentcy of the problem.
Any idea?
Thanks
