GP100 cylinder binds


April 26, 2009, 11:05 PM
I had the Ruger GP100 at the range the other day. I fired six rounds DA and ejected the cases with a sharp rap on the ejector rod with the edge of my hand. When I tried to close the reloaded cylinder it wouldn't close and i didn't shoot any more. The cylinder can be closed in certain positions in its rotation but won't cycle through one "tight" spot in the action. I had the store where I bought it send it back to Ruger for repairs. Any thoughts on what caused the new issue?

I thought I had a headspace problem with this gun when i first bought it, but i didn't send it back. here's the thread about that:

Were you shooting reloads? If so you might have shot too light a load and some unburnt powder got under the ejector which would bind the cylinder. Even if they weren't reloads there might be some dirt under there.

nope, not caused by crap under the ejector. the only six rounds i fired at the range that day were factory .38 special rounds.

your ejector rod may have a very slight bow in it. happened to me once on a smith 13.

The cylinder binding issue is common on GP's. I've owned 3 GP's and 2 of them had that problem. It didn't occur that early in its shooting though. Ruger will take care of you, but you'll have to wait a couple of months to get your piece back.

If it binds at one point in the rotation more than others, it is likely a bent center pin (or whatever Ruger call that part) or a high spot on the cylinder. Bill G mentioned a bowed ejector rod, and with an S&W, he would be right, (bowed or bent) as I had a Model 60 with that very problem, but the GP100's ejector rod does not turn with the cylinder, so it would not be a factor in this case. Ruger's CS has a good reputation for taking care of folks.

i`ve owned many GPs & only had one to bind & it was a headspace problem.
sounds like you`ve covered all the bases a owner is supposed to & maybe more.
call ruger & get a prepaid box out to ya & let em get it rite , don`t worry Ruger will take care of ya.

checked my records on the one that bound up , they replaced the crane asm.

My GP did that when it was new; worked perfectly when empty, but bound up when loaded. Ruger fixed it and it's perfect now. They replaced several parts, but I never understood the cause of the problem.

Had a timing issue on two chambers and a binding problem on my GP.

Sent it to the Ruger Warranty Center in Quebec. It was back in 2-3 weeks problem solved. Works perfectly now.
