Question regarding Ruger GP 100

I own a Ruger GP100. It's approximately two years old and has been treated very gently. Timing is on and there is no endshake. But I have found a glitch. A few weeks ago I was doing a standard functions check and had the age old adage confirmed (again) that if it's mechanical it can break.

Like all modern revolvers when the hammer is cocked I can't swing out the cylinder. But when the cylinder is swung out I can cock the hammer. I estimate 50% of the time I can't cock the hammer, but the other 50% it cocks with no resistance whatsoever.

Now I have contacted Ruger and the company advises that I ship it back to them ASAP to be worked on. No big surprise there in this age of liability.There is a good chance that there will be no charge though there is no promise of that - naturally. Of course I would have to pay FedEx and ship my revolver across the United States (Idaho - New Hampshire) and I've heard stories about Ruger's less than speedy service.

So here is my question. Is this a mechanical situation that can effect the revolver's long-term performance? Will it lead to issues with timing, accuracy, light strikes, AD's and so on. I can honestly say that in the past thirty years of shooting I have yet to cock a revolver on the range when the cylinder is swung out. The only time I have done so is to perform the above mentioned functions check. We have a couple really excellent gunsmiths here in the Boise area. Just let them work on it? Or just not worry about it? I'm leaning towards not worrying about it, but I'm not a gunsmith.

Any advice would be welcomed. Thanks.

You should not be able to cock the hammer when the cylinder is out. If the cylinder is IN, the cylinder latch should be in a slightly different position (rocked forward) and allow the hammer to be cocked. If the cylinder is out, the cylinder latch is rocked back and it should prevent the hammer from being cocked. Check the movement of the cylinder latch and determine if the spring is too weak or if the latch itself is broken in some way.

Hope this helps.
