I recently acquired a Colt Diamondback 4" .22 cal. The revolver has a single action firing problem that I believe may be from a slight timing issue. The revolver seems to function flawlessly when operating in double action but when you cock the hammer to fire it in single action mode and pull the trigger when the hammer attempts to drop I think it catches on the hammer strut and will not drop to allow the firing pin to strike the cartridge base. On occasion it will barely touch the hammer strut and drop to the fired position but you can feel it bump the hammer strut as it drops which causes a slight delay.
Has anyone else experienced this in either the Diamondback or Python and if so what did you do to remedy the problem, and is it even possible short of sending the revolver to Colt?
P.S. I forgot to mention that if I swing the cylinder out so the arm is not contacting the ratchet on the cylinder the revolver seems to operates in single action flawlessly and the hammer drops smoothly to the fired position.
