I'm a semi-auto pistol guy that was getting the revolver itch to do some PPC shooting at my local gun club. I did quite a bit of reading here before I decided on a 6" SS GP100. I am so glad I went with it...I absolutely love it! I can't believe I went all these years without shooting revolvers. I do have one concern about my gp100. The cylinder lockup is tight on one side and has a little play on the other side(tight, then dry fire 3 times and it has a bit of play..dry fire 3 more times it's back to tight). Is this to be expected from a mass produced revolver or does mine have a problem?
New to forum and new gp100 owner...question on gp100.

First of all, howdy, and welcome!
The individual bolt notches in the cylinder may vary just a bit, and therefore not lock up equally with the bolt. Then, there is the tension of the hand against the ratchet portion of the cylinder. Each chamber can lockup slightly differently than the others because of these variances. Whether it is enough to matter, I cannot say from where I sit. If you are getting good accuracy, and nothing solid is spitting from the barrel-cylinder gap, you are likely OK.
On the other hand, there may be something structurally wrong with your crane or cylinder assembly. Not likely, but possible.
Do refer to the sticky post at the top of this sub-forum.
By the way, my terminology in this reply is Colt-oriented. Ruger uses different terms for some of the parts. Time was too short for me to get out a manual to translate Coltspeak to Rugerspeak.

I too just bought a Ruger GP100 and after three trips to the range I found that the cylinder was binding a bit. I took it to my dealer and he said: "lets just ship it back to Ruger. You will get back a gun that is better than new. They will go all over it, even to the point of tuning the trigger. When they get a gun back for warranty repair, they make sure everything is perfect because they don't want to see it back again." So sadly, I sent it back, but I know that I will get back a better gun than when I first bought it.
I've done a little more research on the subject....
I've done a little more looking into this and I think it is ok. I have 3 holes that lock up tight and 3 holes that have some play in them(the three of each are side by side)...the center of the 3 loose ones being the loosest( bother me a bit on the center one). Most people are claiming some looseness under full lockup and say accuracy is good. I have only had it at the range once and I didn't bench it so I don't honestly know how accurate it is. I put about 18 .357 rounds through it and 30 or so .38's. I'm going to try and sneak over to the range tonight and see if there is any accuracy difference between the tight and loose lockup holes.

The tite 1s will loosen up to match the rest of em. & I have a 6"SS that`s approching 7,000 rnds. I tested the Lyman 357446 boolit last week & I shot a 1 hole group at 30 yds.
The lock cuts on the cyl & latch catch trouble when dry firing with that big heavy cyl spinnin , so if ya dry fire to "break in" the action do so in a slow deliberate pulls !!
& congratulations on your purchase !!!!

Are you saying that shooting it DA quickly with live ammo will not peen the notches, but doing so with empty chambers will?

I have a 6" SS GP100 and it is a very well made revolver.
All my cylinders have equal amount of play at lockup and my understanding is that it is normal. I believe with most revolvers there is supposed to be rotational play. This allows the cylinder to move/adjust as the bullet moves through the cylinder gap and forcing cone.
The most knowledgeable information on the GP100 that I am aware of comes from Iowegan at rugerform.net. Give that a try for the definitive answer on the GP100.
Have fun the the GP. I love mine.

Made it to the range for some accuracy testing..pics
Well I quick ran over to the 25 yard indoor range and did some rested accuracy testing(shot double action). I guess its shooting pretty good. I couldn't tell too much of a difference between the tight and loose positions. I was able to shoot around 3-4" groups with it at 25 yards(i'm a cheap ass and taped holes between tests). The last target pictured below was shot standing with a two hand grip shooting double action....shot damn near as good as I did rested. What do most of you guys shoot for groups rested at 25 yards with factory 38spl ammo? I was also having a little trouble seeing the front sight clearly so I'm sure that didn't help with my groups either. The only thing I have done to it is I replaced the hammer and trigger return springs both with the 10lb springs from Wolff and I also polished some of the easy access trigger surfaces with some chrome polish....has an excellent double action trigger now. I was concerned the 10lb hammer spring would cause light strikes but I didn't have any and the primers are dented just as heavy as the stock springs dented them. Anyway, here are a few pics.

I have a Ruger GP-100 357 Mag.with the 6" Barrel that I love to shoot.
I don't know how far away the Target was but I was hitting the same Target My Brother in Law was hitting with His AR-15.
I wasn't getting Bulls eyes but I was hitting fairly close to it.
The GP-100 is a great Fire Arm and very accurate.

I`m sayin that wear will be accellerated dry firing 1,000s of times.
I have a GP100 that has 7,000 rnds thru it [1/2 da] & dry fired probably as much & just beginnin to show signs of wear ! I have replaced the cyl lock 1 time though.

Revolvers are great. Yours sounds well within bounds and most rangemasters can give you good advice. Buy more revolvers!

with all the snow today I took out one of my brand new Security-Sixes (6-inch barrel) and fooled around with it. I took some Flitz and Mothers polish and shined it up and also lubricated it and dry-fired it some. After just an hour, I couldn't believe how great it looked and felt. In fact, as I hefted it, I was glad I was able to get one before the heavier GP100s came out.
Both are great guns, but a SS 6-inch is such a great outdoor gun that Ruger never should have stopped making it. It balances a bit better than the 4-inch GP100, yet it's a full six-incher.
