Is it me or is it my Glock?

Reptile · Sep 8, 2017

I took my Glock 19 to the range today for the first time in quite a while. I intended to re-zero the Viridian laser. I started by shooting at 25 feet using the stock Ameriglo sights, which employ a fiber optic front sight. I used a sand bag for support.

My shots grouped OK, but they were about 6 inches low using a six o'clock hold on the bull. Holding directly on the bull didn't improve things much.

I've been shooting 1911s regularly, so I'm wondering if I need to re-learn the Glock or is there a mismatch in the heights of the front and rear sights?

By the way, I never got around to zeroing the laser.

Have someone else shoot the Glock and see if the low POI repeats?

Maybe breaking the wrist downward?

I had the pistol resting firmly on a sand bag, so there was little, if any, movement. Next time out I'll let someone else try it.

Ah, I must've glazed over that in the OP.

FWIW, I've had times where I had a bitch of a time getting reacquainted with a particular handgun, for whatever reason. Mostly, it turns out to be I'm overthinking things.

Sometimes (for me anyways), it's best to just walk up to the line fresh, not think about anything, and just run a mag thru and let the shots hit where they hit.

Maybe try shooting one of the laser training rounds and see if problem persists?

I'd been trained to have the top of my front sight at the bottom of the bullseye. With the Glock, I need to cover the bullseye. YMMV.

My Sig is the same way and I hate it.

Well, the front sight center finally fell out so I called Sig to let them know that it was 4" low at 25 feet and they told me that I should cover the bull. I told them that I didn't like that and they said they can send me a taller sight. They sent me (free of charge) the highest sight they had and I still have to aim a bit high as opposed to making a lollipop sight picture. I have not shot a Glock that had the same issue but you may want to look into a different sight height.

Go back to basics and do a few repetitions of dry fire and make sure your sight picture doesn't change when the trigger breaks. Try balancing a dime on the front sight and make sure it doesn't move or fall off when the trigger breaks. Or its time for a red dot because they're easier to pick up than irons. Especially with people with deteriorating eye sight.

My Beretta 92FS shoots high and right when I first fired it. Maybe it was me...maybe a different loading would help. Right after that I fired my Sig P226...a bit right but ok otherwise...and a much tighter group then the Beretta. It his a sweet shooting pistol. That was with Speer 115 grain FMJ. I have some other brands and loadings to try and see if that might make a difference. At the same outing I fired my Colt Delta Elite 10mm and the first shots were in the x-ring and a much tighter grouping than the others. I do like single-action autos...1911's in particular.

Combat sights. Don't do six o'clock hold. You should be cutting your target in half with the top ledge of your front sight

alucard0822 · Sep 11, 2017

depending on the model and ammo, I either cut the target or line up the sights and put the dot over the bullseye to hit center. I've gotten used to it, cutting the bullseye is more precice for me than the old 6:00 where you will hit a couple inches above the sight. Shot placement will vary by several factors, and a couple inches off center doesn't really matter as long as your groups are in a consistent spot, slowly shooting small groups on top of a bullseye is pretty much the opposite of combat shooting, and not what the pistol was designed to do.

Reptile · Sep 11, 2017

All advice accepted and appreciated. Now, I'll put it in practice.

ken792 · Sep 11, 2017

What kind of ammo are you using? Lighter, faster ammo prints lower, but I don't think it should be that low. My mouse fart 147gr 9mm loads print a little high at normal distances with my OEM Glock night sights. They actually have a perfect 100yd zero.

My friends usually have good results with Ameriglo. I would think that the sight heights are correct, since that's a critical part of the sight.

You go shorter on front sight if shooting low.

Isn't that a 6 o'clock hold? If he has Ameriglo fiber optic sights, I would thing the front dot should be covering the target.

OP just have someone else shoot it and see, as long as you know they are proficient with these types of firearms.

I would recommend having someone else that shoots Glocks most of the time take a few shots with it and see if anything changes (without the laser). Then decide from there whether or not the iron sights might be off. If it's not off, then it's probably getting back into the groove of using the Glocks. Glocks have a different grip angle vs. 1911s, so that may be a factor.

Testing is the only way to find out.

That would be a Taller Rear sight.

How did it shoot with the actual stock sights ? ( the OEM , not the 'glows.)

I started out with the idea of wanting a social pistol to hit " dead on " , but eventually learned better . I want my poi to be just barely on top of the front sight , instead of being hidden behind front sight. Allowing for group of up to 1in radius ( 2in dia) , this would be a group center about 1in high @ 25yds.

At 5-10yds the offset can be ignored, and treated as if dead on . For long shots, much easier to get hits out to 50-75yds ( depending on velocity) than with dead on, or especially if hitting low @ 25 .

...they were about 6 inches low using a six o'clock hold.

I'm with Butcher on this. The Glock is strictly a combat piece, which is one reason I personally don't much care for them. You most likely can buy adjustable sights for these guns, but the sights on mine shoot at point of aim...exactly. As some guy quipped at the range, “Where are you going to find a six o'clock hold on a bad guy?"

Three options: 1) file a bit off the front sight; 2) buy adjustable rear sights or 3) hold sights steady on target. The Glock, out of the box, shot right at point of aim and I've never had to change it. If I aim low, I shoot low.

I've got a Ruger Speed-Six that shoots low at point of aim. I did some aggressive filing of the front sight, then shot again. This time it shot right on. If I hold at six o'clock, the Gun shoots low. It's set to shoot right on with lighter bullets. It's got a 3-inch barrel and is one of the sweetest guns I have. When it shoots heavier, slow bullets, it shoots low and left. I have to just aim at the upper right part of the target. My dad grew up in the country at a time few people could afford owning more than one gun. He had an old Remington 34 and could drive tacks with it.

travistheone · Sep 13, 2017

there is a close to zero chance it is the gun. aim higher.

Magnumite · Sep 13, 2017

How sights are regulated truly is personal preference based on working know. Way back I asked one high power shooter what was the best way to use peep sights - adjust the sights to center the bullseye at each distance or center the front sight post. I knew of shooters using both. His reply was, "That is one of the great mysteries of life".

I prefer shot groups to be just above the front post as well. That is where I regulate my fixed sight guns for a given load, about and inch to 1.5" at 25 yards.

Cutting my shooting teeth in the bullseye arena and using that adjustment for years I automatically adjust to it at different distances when using adjustable target type sights. From what I have experienced, if the shooter knows it trajectory, it is probably one of the best adjustments out there for a few good reasons.

Magnum guns are a little different adjustment.

Is it me or is it my Glock?
