S&W 67 problem (large image)

*Originally posted 9/12*

I was just dry firing my M67 with fired brass cases when the trigger and hammer locked up. I was able to open the cylinder and noticed that the protruding part of the slide stop will not go down entirely, thus locking up the system.

The revolver was returned to the factory less than a year ago for a tune up and has worked great since.

I am not experienced with gunsmithing and have never removed the sideplate from this gun, althoug looking at the slotted screws I can see that it has been done before. Does this sound like a problem that is easily solved at home without a gunsmiths tool bag?

I managed to tap off the sideplate with the end of a screwdriver. No prying was needed, but it does shed some light on the slightly bent corner which has never laid flush. I'm guessing that a previous owner can be thanked for that.

I took a closeup of the internals and believe that I can see a problem. The three concentric circles are around a coil spring in the lower right corner of the trigger area. The spring looks bent and twisted in the middle, with one end behind the black piece of metal touching the trigger, and a few coils on the right pressing against the frame. Is this typical?

I have no experience in these matters and have yet to put it back together again. The cylinder and crane fell out, but I didn't do anything purposefully to loosen or remove them. Should this happen normally, or did I screw something up? I'm not afraid of tinkering but have no gunsmithing aspirations and am not equipped to tackle any problems. I only went this far because the screws were already banged up and I like to do exploratory observations on mechanical things.

First a couple of minor points:

1)Revolvers don't have slides and therefore don't have slide-stops.

2)The yoke holds the cylinder in, and the yoke is held in my the screw just above the trigger. So, them coming out isn't a big deal, but I've never had them just "jfall out". It shouldn't be hard to take them out, but should take a little effort.


I really can't see the spring well, but the it shouldn't press against the frame. It's not overly difficult to replace that spring, but it does mean most of what you see has to come out (hammer, hand, trigger etc.). Getting the rebound slide and spring out, and then back in again, can be tricky, as well as risky losing the other little springs in there.

I definitely wouldn't try it without some instructions for disassembling and reassembling it. It's probably 10 minutes of a gunsmith's time to replace the spring the way things are now. If you try to do it, and mess things up, at best you'll cause the gunsmith more time to fix things, and at worse break something else. Bring it to a gunsmith. Don't even bother to put the sideplate back on.

Sorry, that was a typo in my original post. I meant to say "cylinder stop".
