trigger lock up on 25-2

[tomcatt51]

I'm starting to think the hand is skipping by a rachet under recoil. Anybody heard of this?

Can't. The only time the hand is engaging the ratchet is before the cylinder stop has the cylinder locked and BEFORE it fires.

Doesn't take much cylinder drag (from too little endshake or crud under the "star" etc) to make the trigger feel like it's locked up.

I had an issue once with a friend's model 29-2, his revolver would inexplicably lock up when the trigger was pulled. I found that the revolver had a short engagement step on the cylinder stop. The trigger would ride over the step allowing it to drop back in the notch of the cylinder before the cylinder rotated past the notch. I installed a new cylinder stop, with a longer engagement step and it solved his problem. I don't know if this is your problem but it is something else to check. Good luck,

That sounds like a possibilty. Thanks for the info.

A 14 and 15 lb didn't work either. I put the original trigger in with just a slightly shortened original spring and the same thing. The trigger return is real positive. Will only lock up shooting live ammo. You can stroke it as fast as you can (dryfire) and not get it to do it. Seems like it locks up after 4 or 5 shots. Could it be a long ratchet or some type of cylinder stop / trigger relationship problem?

Thanks

Just an idea,

have you tried dry firing it with fired cases in the moonclip? If it locks up doing that, its not the gun, but tightness of the moonclips and brass heads.
Moon clips are easy to warp, even just a little could give problems.
Good luck.

I fitted a new cylinder stop last nite and will give it a test fire tommorrow. I think this will do it. Everything feels crisper during the trigger pull and cylinder rotation. I will report back. Thanks for all the help. Got busy with other things for awhile.

The first six went fine and I thought I had it but it started again. Cylinder stop was good. Slight side to side motion, couldn't move the cylinder off the stop, action felt smoother but same deal. Nice 4 way action on the stop. The cylinder was slightly off the stop when it happened. I would have to move the cylinder just a bit and it would click in but the trigger wouldn't budge without opening the gun etc. I am over my head so to the gunsmith it goes. I am a little rusty but still enjoyed learning some new stuff and relearning some things I hadn't done for years. Really wondering what it is. Gotta be a hand or rachet problem maybe?

Thanks for all the input.....

Cylinder gap is too tight. My Taurus 608 had the exact same problem while shooting lead reload ammo. It would shoot jacketed ammo just fine. Try to shoot some jacketed ammo. If it doesn't lock on you, then the culprit is the gap. Brownell sales a tool to cut the back of the barrel. Very easy.

I shoot bowling pins too. Are you shooting in a match?

Most of this shooting was with factory fmj. I didn't mark the cylinder but it may be doing it on the same cylinder hole which is why I'm thinking rachet problem. Shooting in the local gun club bowling pin matches. They have one every Sun.

Check to if the cylinder face is square to the centerline. I worked on a 629 that would bind on the barrel after a few rounds. Increasing the BCG a little or squaring the cylinder (will open the gap too) took care of the problem

and the winner is..........Mr. Finegan.

Smith said the the cylinder was catching on a spot between 2 cylinder holes. The cylinder was slightly out of square and the forcing cone was tight. He straightened the cylinder and widened the cylinder gap a bit.

Thanks for all the feedback, learned something new today.

I'm glad you got it straightened out....I think there is a Joke in there some were...

Happy Shooting
