I picked up NIB Colt CCG a few weeks back and it's doing something odd. When I cycle the slide by hand and go to pull the trigger, it only moves a very small amount then stops like it's being blocked by a safety. After that, when I release the trigger it "clicks" like it's resetting and will fire fine. This only happens when I cycle the slide by hand. If I thumb the hammer down without cycling the trigger depresses fine. If I'm actually shooting and not just dry firing it runs perfect after the first round. Neither of my other Colts or any of my other 1911s do this. Any ideas what the culprit may be here?
