I have an N frame Smith that co ks hard on two chambers. It locks up tight and is very accurate. It just co ks hard on two chambers. It is especially noticeable in double action but is present in single action as well.

I looked at the rachet and hand and nothing looks out of sorts.

The case head may be rubbing on the recoil plate.

It is hard to cook with the cylinder empty as well.

Greetings,

Look for a scuff mark on the cylinder face. (end of barrel rubbing on cylinder) The cylinder may not be perfectly true.

Cheers,

Dave

Also check for debris under the extractor star. Sometimes that causes a problem, too.

Hope this helps.

Been dropped lately? Movie style flips to open or close are very hard on cranes.

Long distance diagnosis is kind of hard. One thing that will exhibit your symptoms is a bent crane. Not to hard to fix, if you know what you are doing, but a bear to talk someone through.

I have a model 19, same problem. Pretty sure that either the crane or the extractor rod is bent.

I'm with mk42. Bent crane would be a great place to start looking. Doesn't have to be from flipping it shut.

Another vote for bent crane

I may also vote for crazy cylinder pin allignment. I didn't see where you said how many rounds have been through it.
That can be factory, poor cleaning / polishing, something in the pin /cylinder interface,.lousy 'squaring" of the cylinder from manufacturing, poor / inconsistent machining at hammer side of cylinder, or crazy something afterwards. If it was a frame / hand / etc issue - it would be with every time I would think.

Take the cylinder and crane out by removing the front side plate screw. If you shoot cast the crane ejector rod gets pretty gunked up. Yes... I know it only hangs up on two chambers but it's a pretty easy check/fix. Is it a gun you just aquired or have you had it a while and the problem just cropped up?

It was crud under the ejector. Oops.

Do I get a prize???:drinks:

I'm glad you found the problem and it wasn't something that required the services of a gunsmith. That's actually a pretty common problem with double action revolvers, since it's not an area most people clean, due to the fact that it's kind of hidden when the cylinder is open. I got in the habit of using an old toothbrush for cleaning that area back when I was a rangemaster, but it's easily overlooked.

Hope this helps.

Also a couple of the snap caps have high "primers"

After fixing a problem that wasn't a problem that could have gotten very , very , expensive on a Colt 1917 that resembled this set up I put a sign over the bench .
KISS
Keep it simple stupid .
Clean it and lube it before you fix it .

I always applied it to cars and airplanes but I was about 6-7 yr out of the annual plugs and quarterly points weekend routines and forgot those sometimes hard lessons .

Glad it wasn't anything serious that required surgery.
