Need a little help on a s&w 681

[Nutbustd]

Hi everybody. I need an answer, now I know they are $5 bucks now but this was has me a little stumped. I have a S&W 681 4 inch. Serial AAH8XX. When I cock the hammer in SA the hammer is just above the back strap and stops. If I put a little more pressure on the hammer it after the 1st cock it seems to cock again and the hammer is on the backstrap. It feels like it is slipping inside. I took the side plate off and found the hammer where it engages the trigger will slip past the cutout for the little spur on the hammer. So it feels like it has double cocked. In both instances the trigger will move. My question is what controls the stopping point of a cocked hammer? or is this a case of a worn hammer or trigger? I want to get this corrected and if I have to purchase new parts so be it. Has anyone heard of this or corrected this issue? thank you for any thoughts or suggestions. Nutbustd

Eeek, I'd get on the phone to S&W and describe the problem. I'm not sure exactly what you are describing, but it sounds to be the result of an idiot with a dremel. The hammer at no time should touch the backstrap, as you well know. Whether a new hammer is required, a trigger or both, I'm not certain. So I'd either send it to S&W or take it to a good local gunsmith. Those parts aren't usually drop in items either, they often require hand fitting.

When the hammer is cocked, it cams the trigger upward on the SA sear. What exactly stops it, I'm not sure.
