Ok, here is goes, i bought a used gp-100 low round count not over 1000, took it up to the range, fired 60 to 70 38 spl reloads then the loaded it up with another six and this happened----- the cylinder would not rotate, the hammer would not even go to the half cocked position, and the cylinder release would not open, after about one m inute of tinkering and jamming on every part possible the cylinder opened and it worked fine again!, i go home do an hour worth of cleaning! Went up again yesterday and the same thing happened again! Wtf! Took it to 3 gun smiths and they looked it over and said there was no problems everything was good to go, it was like they didnt belive me this happened twice! In a week! Nuts! Any other ideas what could be wrong with this piece? I thought the wheel guns are supposed to be reliable? Seems like junk to me! Let me know some other suggestions or if anyone has ever experienced something like this thanks alot!

Just a thought....I had similar probs with very "Light" reloads in 38. The primers were backing out just enough to "bind" things up real good. It functioned fine with "normal" pressure loads.
Check the "reloads" ???????
 
most likely ammo. drop the trigger out of it and clean it out well with an aerosol cleaner and very lightly lube the contact points. Possibly there is a small bit of crud floating about

I agree with cocked &locked,
 
yes im guessing the ammo also , they were very light loads! what everyone has mentioned about the ammo is also what all the gunsmiths said! i really appreciate the feedback thanks!
 
As has been said several times it is the ammo. I had the same thing happen with my python and it took me forever to figure out that the primers were jamming the cylinder.
 
It's already been said, but I'll say it again - check the primers and the ammo, and if you're not crimping then hit yourself in the forehead for all of us! Primers backing out is hard to work with, but if it's bullets snapping out then a crimp is the cure.

It sounds like an ammo problem for sure, either way.

I have a brand new Ruger Redhawk... I thought it'd be cool to load up some homemade blanks (i.e. primers in empty cases).

Well, I fired the first one and it jammed up as you described. I was shocked as I had never heard of this or seen it before. I put two and two together quick though and realized there needs to be force on the brass in order to keep the primer flat and seated.

With the really light (or no loads) the primer is able to back out and jam things up.

So..................... sounds like your .38spl ammo is running very light (some of them) :p
 
The OP's problem occured after reloading a full cylinder...so the problem is not a result of light loads or abnormal loads. It is a mechanical problem unrelated to ammo.

This same problem happened with my brand-new GP100 couple years ago....difference is that I have not fired a single shot when the problem happened.

I got home from Reliable gun and started dry-firing (safety rules followed as all guns are always loaded), the gun was unloaded. Within a few pulls of the trigger in double action, the action bound up....the trigger refused to budge at all.

Opened and closed the cylinder many times...the trigger worked again.

Within a few DA cycles, problem returned. This problem arose without firing a single shot on my brand new GP100.

Brought the GP back to Reliable and they told me they'd said it back under warranty. I had to pay for shipping one way:mad: but that is the protocol.

I followed up the repair progress at the Ruger Repair Center in Quebec, I think it was a watch shop or something, strange name for a gun warranty center but their service is impeccable. Spoke a couple of times with Paul the gunsmith/tech. Fine gentleman..I explained to him the problem. He said he'd replace a few parts...no problemo. It was back with me within two weeks of dropping it off at Reliable.

Long story short...quick fix, the GP100 times and locks-up (or carries up) perfectly like the proverbial bank vault, trigger is smooth and livably light in both DA and SA.

Just one of those things that escaped Quality Control.

Yes, the Canadian Repair Station is located in Sainte Martine, Quebec. Goes by the name Location Snap Shots Inc. That is where you'll find Paul. He has repaired my revolver recently. Does good work and seems very quick!

But I thought revolvers were more reliable than autos?:rolleyes:

That may be true, although my issue wasn't a reliability issue. It was hitting 12 inches too high @ 20 Yds. Even with the sight bottomed down it was still 4 inches too high.
 
Had the exact same problem with my GP100, It's 1 of 2 things:

1) Primers aren't seated fully

OR

2) You NEED to crimp! As the bullets will work themselves out after each firing

......also check the bullet seating depth

.....if the problem still persists after double checking these things, then it may be the revolver
