Colt Det. Spl. 3rd issue shrouded barrel version- in double action every so often, bolt drops between cylinder notches -Bad News. When pulling trigger slowly in double action sometimes its ok but eventually this will occur. In singleaction No problem timing is fine and bolt engagement is fine lock up is tight Only problem is this double action issue Which unfortunately is a big issue. Has anyone had this problem and how did you fix? I know i can send it to Colt but I'd rather know what is causing problem and then fix myself using Kunhausen manual. Looking for someone who has actually done some Smithing on these colts.
