Weird DA problem with 28-2

[Ron H.]

Greetings, all:

I'm having a weird problem with my 28-2 in double-action that I hope someone can help with.

Every so often, the action will completely stop about halfway through the trigger stroke--dead stop, no further forward movement possible. If I let the hammer back down, the cylinder will rotate back, but not forward. This happens only in double-action, never in single-action.

The problem is intermittent. It doesn't do it every time, or even every six times, so it doesn't seem to involve one particular chamber. It only happens when the gun is loaded, either with actual ammo or with snap caps. It seems to happen more often if the muzzle has been elevated.

I can't see anything obviously wrong with the hand, ratchet, cylinder stop, or cylinder stop notches, nor can I find any burrs or irregularities on the recoil shield that would catch case heads. No burrs on the rear face of the cylinder or extractor, either. Barrel-to-cylinder gap is good on all chambers and seems consistent throughout the cycle.

Any ideas?

Thanks, and Semper Fi.

Ron H.

I really hope this isn't your problem, but the only time a Smith revolver ever did that to me was when it had a broken trigger stud. ( I used to believe S&W revolvers never broke! ) The factory fixed it...on my nickle, and now it's all good.

Wierd DA Problem with 28-2

Ron, Not being able to actually function-check your revolver it is somewhat difficult to identify exactly what is causing your problem, however, if the parts you mentioned examining are indeed functioning properly and the malfunction occurs only in double-action, the next thing I would suspect is the DA sear on the hammer. The sear only comes into play in double-action and as you may already know, there is a tiny sear spring that fits between the rear of the sear lever and front of the hammer. To check the sear remove the hammer from the frame and carefully drive out the sear pin which connects the two and be sure you capture that little spring. It is so small that if it flies out onto the deck you may never find it again (Don't ask me how I know this. Can you read Charlie Foxtrot?) Check the little spring (if it was in there) and see if it is kinked or otherwise mangled. Sometime they become partially unseated causing irregular functioning of the sear. If the spring has come complety out will usually malfunction all the time. If the spring looks o.k. place one end of the spring in the small pocket(hole) on rear of the sear lever and the other end into the pocket on the front edge of the hammer (keep it from kinking or escaping-see CF above) and drive the pin back throut the hammer and sear. Re-assemble everything and function check. May or may not fix the problem(sure hope so). Hope this helps in some small way.

Also, thank you for your service, Marine.

Guys, thanks for the input. Looks like it's time to dust off the Kuhnhausen book and see what's going on inside this thing.

Oh, and I'm rather more familiar with "Charlie Foxtrot" than I'd prefer.

Thanks again, and Semper Fi.

I had a problem with some of the symtoms you describe on a 657. There was a burr on the extractor star that the hand would catch and the gun would lock up because the cylinder stop would engage the cylinder before the sear would release.

It only happened in DA and only if the trigger was short stroked then pulled again at that chamber.

I had the exact same problem with a 28-2. I replaced the cylinder stop - although eyeballing it showed no obvious problems, but I had a spare and they're cheap - and the problem went away never to return.

I'm going to second what a previous poster said: Trigger stud probably snapped. Same thing happened to me once with a 29.
