SP101 locking up. Is it me or the gun?

[shamus]

This is a hard-to-phrase question, but here it goes: every once in a blue moon, when I close the cylinder on my sp101 and pull the trigger, nothing happens. Trigger can't move the cylinder and hammer can not be cocked back. The lockwork is locked up as if I don't have the cylinder fully closed, but I do. When this happens I rotate the cylnder a tiny bit and everything works fine. Sometimes I swing the cylinder out and re-close it and eveything works fine. I've been unable to duplicate this "locking up" not matter how I close the cylinder, and I've spent time trying.

Anyone have an explanation? I figure when this happens it’s because something is not fully engaging when the cylinder is closed. Or am I doing somethng wrong?

Well, we all have to rotate the cylinder a tiny bit after closing it to get it to click into place. I do it automatically and never think of it.

If that's all you're talking about--it's you.

If it's not, I see a visit to a gunsmith in your future.

Sounds to me like there might be a piece of gunk or trash or something in the action. You may need to give it a complete cleaning. Try cleaning it first and if it continues take it to a gunsmith.

It was bought used. I thoroughly cleaned it (trigger assembly removed, etc) and the springs have been replaced with factory standard ones from wolff. I can see no burrs or anything wrong.

This has only happened three times and I've never been able to replicate it, no matter how I try. I've closed it and rotated the cylinder so things are not in place, and it still works (when I squeeze the trigger, the cylinder click itself into place.).

I'm thinking it may be me.

Sorry, wrong thread. Please disregard.

This used to happen to my lamented, departed SP101 after I dripped too much oil into the cylinder-stop area of the trigger-group assembly. What was happening is that the trigger was not returning fully forward for some reason, and I would have to either jiggle the cylinder or joggle the trigger to restore function. Sounds weird, but through trial & error I discovered that it worked perfectly when unlubricated, and I finally learned to put only one(1) drop of oil in there, and use a Q-tip to soak up/distribute the oil through the rest of the mechanism.
