Ruger GP100: consistently to the left

[recoiladdict]

I have noticed that my Ruger GP100 shoots to the left invariably from where I aim. If I deliberately aim slightly right, it hits dead on every time. After shooting through probably 1000 rounds at this point, I can say definitively that this is the gun and not my technique.

(before you comment, yes I know I can adjust my windage to accomodate).

The reason I hesitate to merely adjust my windage and continue unabated, is that I noticed something about the gun's muzzle that seemed odd. I haven't much of a clue about ballistics or the physics of gun design and performance, but...the rifle grooves are noticeably deeper on one side of the muzzle than the other. On the right side of the muzzle cross section (face on view of the muzzle), the rifling is apparent. THe left side of the muzzle is smooth on its interior surface. My immediate thought is that this might have somehting to do with the regular innacuracy of the gun...

Is this something that one would consider a factory QC issue or should I just adjust my rear sight and quit whining?

Maybe it's some kind of wear pattern?

bought new just two months ago

You're able to hit "dead on" with a little work. This isn't inaccuracy. Adjust your rear sight and have fun!

Get used to it.......
I bought a NIB 4" GP100 that had more problems than I care to discuss; Ruger replaced damn near everything and it is the most inaccurate gun I own.
Also, Ruger told me if I wanted to "test accuracy I should use 110 gr Winchester like they did during test fire". I told the idiot on the phone if I wanted something accurate around 110 gr I would use one of my 9mm's.
Ruger can go..........

Have you contacted Ruger and described this? Send them a pic maybe?....They'll make good on any factory flaw.

Adjust sight and continue to shoot. I can't ever remember getting a new gun with adj sights shoot dead on out of the box.

My immediate thought is that this might have somehting to do with the regular innacuracy of the gun...


The gun shoots accurately (groups)? It is just shooting left? Correct?

If it's consistently shooting to the same place to the left, it's probably the sights. Adjust them until you are shooting center. If there are still issues send it to Ruger.

The only gun I got that shoots to point of aim out of the box is a Ruger Speed-Six. I have another one I had to file the front sight down on, though, so it's the luck of the draw.

Don't get into the groove thickness thing or you'll end up going crazy. The same blades drill all of the lands and grooves, so it's unlikely that there's anything wrong with your gun. Besides, the grooves just stabilize the bullet; they don't do much else.

Everything is shooting to the left these days, even Congress. All one has to do is make the right changes. : )

If you find that you're moving the sight blade all the way to the right to get it to center, then you've got a problem. Chances are, though, that your gun is fine. Rugers are good guns. Solid, too.

So, you aim to the right and it's "dead on?" Does that mean that when you aim to the right, it hits in the middle where you wanted it to go in the first place? Or does it hit exactly where you were actually aiming?

FIRST of all, make sure it's not YOU.

Put some empty cases in there, along with some live rounds. Spin the cylinder then gently close it. Shoot as per normal. pay special attention to the front sight when it goes "click." This may solve that mystery for you.

I have watched my sights when pulling through the trigger release. No movement to speak of. The gun does shoot super tight groups, though. I have on many occasions put 4 bullets through two holes. I will adjust my sights. Surely that will do the trick. I just wondered if the groove depth variance from one side of the muzzle to the other was worth worrying about. But that is irrelevant if the gun shoots tight groups and reasonable sight adjustment fixes things.

My guess is that you are right handed. Go to the Bullseye home page and look up the "wheel of misfortune." for guidance.

It's usually the shooter. Have you noticed that people rarely complain about shooting consistently to the right?

I've been working with this book lately - Master Handgunner: The mechanics of X-count shooting, and the importance of finger placement and a straight-back pull are stressed throughout the text. Grip and pull are not instinctive and the pressure required to pull the the GP100 trigger may be pulling the muzzle.

 

[IlikeSA]

Why not let a friend shoot it and see? I had that problem with my first pistol, took it to the range, let another shooter shoot it, and saw it was my problem, not the pistol.

 

[BCRider]

Maybe see what a smith says about the rifling. And then go from there if he indicates that it's not a common thing.

 

[The Lone Haranguer]

If it is an adjustable sight model and not so far off that the sight would run out of travel, move the sight to the right and be done with it. This is a little more difficult on a fixed-sight model.

 

[Magnumite]

how far from center and at what distance?

 

[BCRider]

Another thought.... You didn't mention how much revolver vs semi auto shooting you're doing. Revolvers want the trigger finger to be well through to the point that the last joint of your finger is the part pulling the trigger. If you're mostly a semi auto shooter this may have slipped your mind. Not getting the trigger finger through far enough would certainly pull your groups off to the left by enough to make a 3'ish inch diffference at around 10 to 12 yards.

 

[recoiladdict]

Confirmed. Trigger finger placement. I WAS pulling the trigger like a semiauto trigger. Bullseye.

Thank you all for your comments and information.

There is nothing wrong with using the pad of the finger when shooting a revolver - especially in SA mode. Many revolver shooters do use the pad of the trigger finger for single and double action shooting. Their group placement is not effected by it. It is actually proven to be fast in DA shooting than placing the last joint on the trigger.
