2000 Shots Later: Ruger GP100 w/3" Bbl...

Hello. Back in 2003, I purchased a NIB Ruger GP100 w/3" bbl and the "short shroud" at a nice price. I'd been trying to find a like-new S&W Model 681 to replace the excellent one that I'd owned a few years before and foolishly traded away.

I was surprised at the nice double-action pull on the Ruger but a tad disappointed in the single-action pull; it just wasn't as nice as on the typical S&W.

At the range I was definitely not disappointed in the revolver's performance. It was utterly reliable and a peach to shoot with any of the 357 loads tried. For those who might be interested, results and observations are here:


Since that original report, I've shot approximately 2000 .357 Magnum loads, factory and handloaded, through this revolver. Certainly, this is really not a "long-term" situation, but I think it represents enough of one to suggest that the GP100 is most capable of handling more than enough magnum rounds for the most shooters in a lifetime.

The DA pull has gotten better with use and frankly, is as smooth and light as any of my S&W revolvers. The single-action is still not as light and crisp as those on the S&W's, but it is imminently useable.

The factory load I shoot most often in this gun is Winchester's 145-gr. STHP. An "old technology" bullet is used in it to be sure, but it has "worked" nicely for me on critters and groups well in most revolvers I've shot it through. This GP100 is no exception. Today, I used a handload consisting of cast 158-gr. SWC's over 7.0-grains Unique powder. One can certainly go hotter but this one's worked nicely for me and seems close enough to the Winchester STHP load to allow for more economical shooting as a substitute for this usual "carry round." Based on ten-shot strings fired 10' from the chronograph screens, the Winchester 145-gr. STHP averages 1197 ft/sec with a standard deviation of 17. The CSWC handload does 1154 ft/sec with the same SD. I also used a Rainier 158-gr. PFP over the same powder charge just to see what it would do, but didn't chronograph it...yet.

Seated and with wrists braced, this group was shot slow-fire and in single-action using the SWC handload. POA was the center of the bullseye. It groups satisfactorily albeit a tad high at 25 & 50 yards, at least for my eyes.

I repeated the process for the Rainier handload but fired in double-action. To me, the groups are equivalent. This was not really much of a surprise but a reaffirmation that some precise work can be done double-action. Back in my police PPC days, like many other shooters, I opted to shoot all of the stages, including 50 yards in double-action. To do much good at it, the action must be smooth. We were all shooting either S&W or Colt revolvers then, but this GP100's slick DA lent itself nicely to double-action shooting.

At 25 yards, I did the single-action thing again using a 6 O' Clock hold at the bottom of the bullseye. This is close enough for my shooting "needs" and I was more than happy with the results.

Moving to 10 yards, I fired several "Failure to Stop" drills from a standing position and using a two-hand hold. I didn't have a timer but fired the torso shots as quickly as I could obtain a "flash sight picture." A few shots were a tad farther out than I would have preferred but so the chips fell. The head shots were a bit slower. I would estimate that the torso shots were fired at about 2 shots per second and the head shots at half that. A certain revolver superstar with the initials "JM" has nothing to fear from me!"

After that, I shot falling plates a few times from 10 and 15 yards with the SWC load and shot at a "metal man" from 50 and about 65 yards standing, using both single and double-action. I was surprised that there were more hits than misses; there is no doubt that the misses were due to operator error.

Again, not really all that many shots have been fired through this revolver to constitute true long-term results, but so far I believe that the gun is a very good buy and long lasting. To my eye, it remains a cut below those of the classic S&W but on the range or field or in the "dark place" that doesn't count for much in my opinion.
I cannot say that it would be true for all Rugers, but this one has proven itself to be capable of extremely smooth double-action use as it came from the box, though its single-action doesn't match the Smith & Wesson's, at least not on my gun.

I like this revolver very much, more than when I initially purchased it and plan to continue using it both at the range and as a carry gun in the woods. It is also a "house gun" and one that is always loaded.

The crane-to-frame fit has remained constant with no "slop" and the revolver's cylinder remains timed nicely. It locks soundly before the hammer drops. The gun has never bound up when firing...at least to 300 shots. It has not been fired more than that between cleanings. Leading has been very minor and easily removed, indicating a smoothly bored barrel.

This revolver is stock; no changes whatsoever have been made with it. While this is entirely subjective to the individual shooter, I've found the factory stocks to be comfortable and plan on making no changes to this handgun.

In my opinion, the GP100 is a very viable choice for folks wanting a .357 Magnum that should be both long-lasting and easy to handle. It is neither the smallest nor the largest example and certainly not the lightest, but it is not hard to tote and its weight handles the magnum's recoil nicely.

This one remains a keeper.

great review thanks, great shooting and great looking wheel gun. i have been wanting a wheel gun and have been looking into the ruger gp100 i think you just reassured me, i like it and see no reason not to get one! thanks again.

Charles; I just picked up my first GP100 4" yesterday. Haven't had a chance to shoot it yet but I'm glad I read your post about yours as it gives me great confidence in my new(to me) gun. I picked it up for $275 OTD, but since they had a consignment check for me I only had to pay $42.00. I'm really looking forward to my next trip to the range.

Some time back I acquired an almost NIB 4" stainless from an estate. It had an action job from an unknown pro, and the SA and DA were every bit as good as any S&W I have ever seen. Like any GP, it is a little on the big and heavy side, but I have old "Sixes" for the CCW role and this makes a nice field gun in a Bianchi UM84R holster.

I find myself taking this one out more often as I shoot it better than almost any other wheelgun I own. The weight and the "rubber" stocks combine to make shooting full 125 grain loads actually enjoyable.

If the day of the revolver in police work had not been ending just about when the GPs came out they would have had a great career on the street. They're a "whole lotta gun" in more ways than one.

Good review and real good shooting. I have the same model, and it constantly rides in the car when I am on the road, but I do not shoot it quite as good as you. I reload, so I should practice more with it. Did you settle on those loads for most of your shooting? Old 112

Hello. Yes, my practice load is one of the two handloads mentioned and I normally load the gun with the Winchester's for carry.

Great article, Steve. Thanks for posting. Nice shooting, BTW!

Dang! Makes me want one now even MORE!

May 12, 2007, 04:46 PM
That is my daughter's 2nd most favorite pistol. Her #1 is the Ruger Bearcat .22LR. If she sees this, I'm in trouble.

Nice pics, and nice report.

Stephen: 2,000 rounds? That isn't even enough to start smooting up the action yet.:D

Glad it's working out for you. Those are one of, if not the best, all purpose 357s out there.

Mr. Camp, Excellent Review.

Now a sincere thank you from me, and a lady friend.

I know a lady that is really fond of the 3 K frames.
Hers are extremely sentimental, since the passing of a dad and uncle.

I shared your initial review of this gun, along with other reviews from your site with this lady.
She made the effort and while out of town was able to shoot this gun at a range.

She ordered one through her local gun person.
No, it does not have the S&W single action, nor the deep bluing, or sentimental attachment.

The gun works, has done so flawlessly and her loading is also the STHP.
This gun does CCW, Home, Rural Property duty.

Hers is bone stock, except she did take a emery board to smooth and shape the thumb rest a bit, as her thumb and rest did not 'fit" just right.

She bought a second one, and will be getting a third.
She was raised to be redundant in firearms.

It is we that sincerely thank you sir!

Hello. Thanks for the "thank you". Glad to have been of service and that the post was of use.

An individual I know had his blued GP100 spend a winter(4 1/2 months) in a snow bank. Bad holster choice was the cause.

Gun was found by a cross country skier in the early spring, and turned into police.

He cleaned it up, and other than the finish being a little rough, it's just fine. Action, bore and cylinder are still in great shape.

Did your lady friend get the one with the small grip and fixed sights?

Yes Sir.
She says it reminds her of the 3" RB HB Kframe [ Model 64]
Size 6.5 or maybe size 7 surgical glove fits her hand.
Left hand ring finger size 6.5.
That help any?

Excellent weapon. Should last her the rest of her life. And if worst comes to worst(hope it never does) it has more *thunk factor* than a j frame.

May 16, 2007, 03:03 PM
Sir Steve!

Nice job as always. I have found that the 145 STHP is actually the best load in my Gp 4.0 and my SP 2.5. I really liked your review on the 3 inch SP on your site and around on other boards.

Feel like testing a 2.5 Sp and see if you can get the same kind of results you got from your 3? I doubt there would be much difference.

I would love to see how the 145 STHP would stack up against some of the newer .357 and .38 stuff that is coming out on the market. My SWAG phone book tests still put the 145 STHP as the best round out of these two guns.

God Bless,

Hello. I might be able to shoot/test one of the 2 1/4" guns. A friend of mine carries one as a BUG daily.
