My second non S&W came with disappointment
inaccurate at any distance.
Compared to my 28 it isn't even close, using same ammo,
same range, same hands. To be fair it doesn't have an adjustable rear sight but the same model with one was available
(didn't know) called Ruger they will send me a shipping /return
label. Why wouldn't they just make one model with the adjustable sight ? I don't like to compensate and shoot different ranges, they call it Match Champion more like match bozo
Ive had small problems with two of my Smiths but were easy to correct by myself Loose trigger pin on the sport and loose ejector rod and cylinder release button on the 986

You lost me on that.

Define "not accurate"?

To be fair to Ruger, first, the vast majority of GP 100s have adjustable sights and, second, whether a Ruger is more accurate than a comparable S&W depends on the individual revolvers, how compatible the loads are with them, and how the shooter gets along with the gun. Like Arik, I'd like to know whether you're getting 2" 6 shot groups at 25 yards with your 28 but 2 foot groups with the Ruger or you are having trouble at 5 yards with the Ruger caused by operator error.

Ruger will do you right. I know sending a gun out for repair is not on the top of any of our "to do" lists, but you should have it back in your hands within a couple weeks after you send it out.

As said above "inaccurate" means different things to different people.
Some people label a gun as inaccurate because it doesn't shoot to the
point of aim in their hands which has nothing to do with accuracy. To
be frank you should have bought a gun with adjustable sights to begin
with if that's what you wanted.

I have a 6" stainless GP100 that is a absolute tack driver. It doesn't matter if it is .38spl or .357.

Is this when seated and using a rest? Offhand "accuracy tests" mean little in my experience unless you have adjusted to the grip the new gun requires.

My first thought when I read the OP was "operator issue". Not that I am an expert, quite the contrary. I have guns that I shoot pretty well, others, not so good. But people who shoot better than I can shoot them fine.

It may well be the gun, and maybe you are experienced enough to recognize that off the bat. But I'd be inclined to spend a bit more time with the gun before sending it in.

I wouldn't write Ruger off just yet. I think that you will find the Ruger customer service to be very accommodating. My collection is predominately Smith and Wesson but I also have a some Rugers. My GP100 4" with adjustable sights is my most shot revolver. Barely misses a trip to the range. It is far more accurate than I am and it's made very well.

After some research I found on the parts breakdown list, a front sight .20 shorter .445 vs .465 Ruger sent me one its a Novak dovetail mount fiber optic Installed it and went to the range and was pleasantly surprised at the results
The before and after pics enclosed shooting at 15 yds with reloaded .357 125 gr extreme power pistol 9.5 gr

FWIW, I recently purchased a GP100 Match Champion with adjustable sights.
I waited specifically for the adjustable sight model as I tend to shoot a variety of 38 special loads from this (competition) type of revolver. While I thought the trigger still needed some TLC (which it promptly got) the rest of the gun was very nicely done. As for accuracy it will shoot side by side with my 686 SSR Pro and give up nothing. Oddly enough, the rear sight hasn't been touched as it was right on from the factory.
That said, both of these guns are sporting Fiber Optic front sights which tend to be a little "less precise" and better suited towards ringing steel plates than shooting out the x ring on a slow fire target.

Long story short: I'm not sure about yours but my MC is one of the nicest non-S&W revolvers I've ever owned.

I suggest that whenever you have a handgun that seems inaccurate, hand it to a person you know shoots well for a second opinion.
I've seen a lot of busted egos over "inaccurate" guns.

I would think that a non-adjustable rear sight would affect POI more than group size. Although, if the notch to front-sight width was vastly different then what you are used to, that could affect accuracy.

I strayed in my youth and bought a Ruger single six 22/22 mag 6" and a bull barrel 22-250 M77.......... both were accurate and worked w/o problems.

They should fix things for you......... I never had any problems but have also heard nothing but good about their service.

All the makers want "Stars" when things go wrong............

Hang in there.

I would have gotten the one with adjustable sights had I known it was available, I checked with Novak and they told me they have one in the works for the non adjustable models. I am used to changing from one range to another and find an adjustable the best compromise plus the fact I reload my own

I appreciate your response Dave I am happy with the results I actually fired a friends gp and did well , he fired mine and was way off . I am not the best shot but judging by the group on the first shot the grouping was good but low , off the target. The second after replacing the sight was right on once I found the (sweet spot) I still prefer an adjustable ,as on all my Smiths except the 40 m&p

My old Ruger Speed Six with the 2 2/4 barrel is one of my most accurate handguns when I do my part. Shoots exactly to point of aim with 125 grain .357, factory or my reloads. Non adjustable sights.
