New GP100 end shake question

[JAV8000]

I took the dive and traded in my Taurus 605 .357 snub (since I now have a S&W 638) as down payment on a Ruger GP100 yesterday. I was fondling some other GP100s today and noticed they all had varying amounts of end shake and rotational movement. The specimen I chose has almost no rotational movement at full lockup, but does exhibit a very tiny amount of end shake, probably slightly less than .001 (didn't have feeler gauges with me). This has been the case with most revolvers I have come across. The only revolver I've come across that felt like a vault was an old model 15 (guess they don't build em' like they used to). Most people think I'm being neurotic by thinking this could cause a problem in the future, however Jim March's article above has me thinking I should consider shimming the crane/yoke before shooting the weapon. Ok, so heres the gist of my blathering:

Will shooting this gun with a small amount of stock end shake cause it to grow rapidly over a short period of time (5000 rounds) using full power .357s about %20 of the time? Do any of you have experience with this specifically on the GP100? I have a hard time believing this frame would stretch vary easily. Should I have it repaired right away?

Thanks in advance!

You can feel a one-thousands (0.001") end shake? I don't believe it uness you are a Class A, Moldmaker or a robot! Plus, you want to shim 0.001? I think that you are obsessing about the inconsequential.

I own a 6 inch ss gp 100 for a couple of years now and all i can tell you is that when people say ''they are tanks'' that about sums it up. Ive shot over a thousand rounds through mine(some very heavy) and its better then new. Before I purchased my Ruger i test fired a Taurus tracker 357 (a rental) HATED IT!.The next visit to the range I rented a 4 inch gp the gun had seen well over 5000 rounds according to the range instructor, it was as tight as new and hit right were I pointed it. My mind was made up.
From all the other sites i have read I have never heard of any real problems with the gp your Ruger will hold up to just about anything. Enjoy your new toy.

I guess it's more of a feeling and seeing thing with a strong light (my Surefire). There's definatly something there, though not much, just a little more light and a VERY tiny movement. Maybe .002 is more realistic. Is this ok for a factory new gun?

My experience with the GP-100...
When I got mine I found that the barrel was not screwed on properly. I couldn't get the sights adjusted properly so I sent it back to Ruger for repairs.
In the past, I've never gotten a defective gun back and actually ever been satisfied with it...
The GP-100 came back in about two weeks. In addition to taking care of the barrel problem, the smiths at Ruger had totally worked over the action and replaced a half dozen other parts just to be sure they got the right thing. The cylinder spins now like its on ball bearings and the action is so smooth!

So I'd say that if your GP-100 does wind up disappointing you in the least, send it in and when it comes back you'll have a whole new point of view about customer service.

Thats good to hear. I like to hear about good customer service. Makes a man feel warm and cozy inside....I guess really I wish they had a couple examples of the 4". I guess I have some time to see if they get any more to cherry pick from while mine's still on lay-away.

Take a visit to www.rugerforum.net.

There are some very very knowledgeable GP100 participants there.

There is a document called the IBOK which is an excellent GP100 reference.

You will have to make 10 posts on the forum before you will get access to the IBOK.

According to the IBOK there is supposed to be .001 to .004 endshake on a GP100. Totally eliminating endshake may cause the gun to bind, also never set the endshake to less that .001.

Go to Rugerforum.net and get the IBOK. You won't regret it.

P.S. Another good Ruger site is www.rugerforum.com

Thanks Herbie1!

Late last night I came across a couple posts on various forums that state GP100s are designed to have a small amount of end shake. I figured the design could handle it, but to be honest, the revolver checkout article on this forum really made it sound like any end shake in a revolver is not good. Perhaps the mods could add a side note in the end shake section about Rugers? I bet some other neurotic mechanic/machinist types have asked it before.

I love a good forum! I've been searching for a good gun-forum-home awhile now. I've been lurking for a little while now and I think this is a great place.

Thank you all for your intelligent input, you put a guys heart at ease! I believe the iron to have .002.-003 end shake and almost zero rotational movement. Should be absolutely perfect! I thought that trigger felt good.....
