GP100 Cylinder Issue?

Yesterday, I purchased a used GP100 (blued 4" model) with a few speedloaders for $440. It is a very old revolver; the guy told me he bought it in 1991. It looks fantastic, especially for its age. The cylinder locks up nice and tight as well. However, when I got it home I noticed that when the cylinder is open, it doesn't always free-spin clockwise. It has no issues turning the other way, but sometimes (not always) it will "hang up" when turning the other way. I don't know how big of an issue this really is, but I'm curious to see if any of you have experience with this. Thanks.
 
Clean it well. Then give it a light touch of oil. Let the oil sit for a few minutes to penetrate. Then wipe it off. Then try it. It could be that it just needs a bit of oil.

Also try taking it out, and shooting it. See how it feels while shooting it.
 
I don't know whether to feel bad, or just amused, that a gun made in 1991 is described as "a very old revolver".

"Very old" by my standards, since I was born in '89 and I've bought only new or lightly used guns up until now. As far as the cylinder goes, I've oiled it twice. It really seems like it's getting hung up on something physically.
 
Get a can of brakleen & blast it out with it , then with compressed air all while pushing the ejector rod to work out the crude & deposits of carbon .

I use Rem oil in this area as it does`nt seem to attract deposits as bad .

& as mentioned pointing it up or down will have a bearing (pun intended) on how free it spins.
 
Decided to do a full disassembly of the gun, and I've got the crane separated from the cylinder. Regardless of cleaning/oiling of all internal parts, it still seems like it doesnt want to spin clockwise most of the time. It still randomly decides to work flawlessly sometimes, then after a few spins, its back to square one. It's very strange. I'm looking at the most basic two pieces involved, and I really can't see what could be the cause. I think I may just take it to a gunsmith to be sure.
 
^^ What he said. I don't think the cylinders on the GP100 are made to disassembled any further then you have already. At least not without the right tools.

I have seperated a cyl from the crane on a Redhawk & twice on a GP .

Fairly simple proceedure but it takes 4 hands to put em back together.

That`s when I went to the flush & blow to clean it .

If I had the time I`d love to build a jig to do it , on second thought no I would`nt !
