The gun is an SP01 with safety. I changed the angle and polished the hammer surface that engages the sear. Now when I press the trigger, there is a click as the sear disengages, but the hammer doesn't fall because the double action mechanism takes over. Continuing the pull it acts like a DA and drops the hammer after about 3mm of the hammer cocking. It doesn't always do this. About half the time the hammer falls like normal.
Do I need a new hammer, or is there a surface I can reduce in the DA mechanism? Or did I just reassemble it wrong? Thanks.
