I have a rugersp101-22 with about 10,000 rounds on it.Today at the range the cylinder locked up 6 or 7 times.I would reload the cylinder then couldn't pull the trigger.I would open the cylinder and rotate it then it would work normally.I'm not tot familiar with revolvers is there a screw coming loose that i should check for or any opinions appreciated.Thanks

I'm pretty mechanically inclined, but with that round count I would take it to a reputable gunsmith or send it to Ruger.

Were you rotating the cylinder until it clicked in a notch after you swung it back into the frame?

 

[LaneP]

When's the last time ole' girl got a good scrub down and lube?

Probably carbon build up on the face of the cylinder binding it up.
If it was a centerfire it might have to do with primer flow back but since its a rimfire, I believe it is carbon build up.
CLEAN the gun and try again.....

Agreed. Carbon and probably lead buildup(it is a .22) on front of cylinder and forcing cone.

I did rotate the cylinder until it clicked.I will clean the forcing cone tonight.I usually clean underneath the star every other time i clean so that area looks pretty good.Will thouroughly clean this weekend and try again.Thanks

Is your ejector rod coming loose, if it is unscrewing itself during shooting it will bind the action.

 

[Three-Five-Seven]

The place where revolvers get fouled that results in sluggishness or stoppage is at the front end of the cylinder boss that contains the base pin. Fouling in this location will affect the end-shake dimension of the gun and cause binding.

You can do what others have suggested, it won't hurt anything. But, you really have to remove the cylinder from the base pin and clean the front of the boss and backside of the frame to do a thorough job.

Wait, I thought revolvers neeeeeevvvverrrr malfunctioned....

My first thought.

I had the same problem with my sp101 .357 right out of the box! I wasn't inclined to have it fixed. I returned it for another one. The Davidson guarantee came in handy.

I don't believe the SP-101 extractor rod is a screw-threaded part, so it is unlikely that it is coming unscrewed.

.22 ammo is filthy stuff. My first guess would be a build-up of crud or a few unburned powder granules under the extractor star, but if the problem goes away after just opening and re-indexing/closing the cylinder, then it's probably crud at the front of the cylinder, where it spins on the crane.

One last possibility would be a loosening of the crane (cylinder) latch screw, allowing the crane (cylinder) latch to occasionally get misaligned and bind-up on closing. Look for the screw under the crane (cylinder) latch, also known as "that button you use to get the cylinder open". The screw passes through the latch from bottom to top; make sure it's not backing out (or missing).

I have a S&W mod 65 that when I used .38 special reload in nickle cases would jamb the cylinder. Nickle is a bit more slippery than brass.

Also make sure the chambers are clean and free from lube. Fouling from .22 can be pretty bad - creating case set against the recoil shield.

Sonoma, One thing that I have found that causes cylinder lock up is back traveling a double action trigger pull. Once you begin a double action trigger pull you can stop, and freeze at any point along the cycle, continue to increase pull and stop again and again but never go backwards or let the the trigger back travel once you have started a pull. You must complete the cycle or you can and will experience a frozen or misaligned lockwork of the revolver. I have learned this the hard way particulerly with S&W revolvers. This is not the answer to all just one way I have found to jam a cylinder. With as many rounds as she's fired for you I think she has earned a closer look by a gunsmith don't you?

 

[ArmoryDoc]

The slightest bit of unburned powder residue under the extractor star of my Smith 617 will cause that.

no Taurus bashing here yet?:crying:

 

[Bill Lumberg]

I've owned two Taurus UL models that siezed up before I even got a box of ammo through them. But those were UL models. The SP101's are some of the nicest revolvers out there. I'd bet on filth or plain old wear and tear in this case.

My M85 UL has developed timing issues which locks up the cylinder while firing in double action mode.

Might be something to check.

This happens to my GP-100. I give the front of the cylinder a quick wipe with a piece of abrasive pad and keep shooting.
