My CZ 75 SP01 Safety has a CGW upgrade working well over 800 rounds thru it yesterday. I was dry firing and the hammer locked back. Pull the trigger and nothing, hammer doesn't move. Trigger has tension. Trigger spring good, sear cage spring is working admin place. Took sear cage out, hammer releases. Rebuild, sock hammer and lock. Any ideas?
