You are talking about the double-action sear that is hinged in the front of the hammer? If correct the problem is probably that the sear was not fit correctly or has been replaced and not fit properly! The sear is not a drop-in part, and a new one will have to be fit too!


1) If the sear is catching on the trigger instead of swinging forward freely then it needs to be either shortened slightly or slight bevel cut on the back corner of the sear (the hammer side). A very common error when "Bubba" is fitting a new sear is he doesn't cut the bevel!


2) If the sear is not "let-out" far enough it could cause the same problem. With the side plate off note carefully the position of the sear relative to the hammer with everything "at-rest". Then cock the hammer. Is the sear in the same position, or is it slightly farther out at the bottom? If it is in the same position then the stop at the top of the sear needs to be trimmed slightly to "let-out" the sear slightly. If it is farther out then the problem is at the bottom end, see above.


"Google" this: "S&W double-action sear bevel" and you will find numerous links on the S&W Forum, You Tube, etc that may help. Look all the way at the bottom of this thread too and you should find links to similar threads. This is a common problem with used guns or ones repaired by someone who doesn't know what he is doing.


Before doing anything you should buy a copy of Jerry Khunhausen's book "The S&W Revolver, a Shop Manual". It is available from Brownells, Amazon and many other book sellers. It is about $25-30 but well worth the money as it shows clearly how to make almost any repair to a S&W revolver!
