I shot a dot torture drill today at 5 yards with my Glock 23 with Storm Lake barrel, 140 grain MBC handloads. I noticed I was favoring left and a little low. Careful trigger presses etc. so after I was done (failed, by the way; pulled shot #47 low) i put up a B8 at 10 yards and shot 10 shots offhand. Group was nice and tight but about 7 o'clock in the 9 ring. I confirmed my rear sight was centered, and tried my AIM surplus 9mm conversion barrel, which previous evaluations had showed hit somewhat low.

I shot another 10 rounds on a fresh B8 with Magtech ball, and the group was not super great but it was indeed lower and even more left.

So then I painted a fresh steel torso at 18 yards and shot a full magazine and they were all dead center in about a softball sized group.

Me not get. Is it my eyes?
 
Could it be that close target focus amplifies slight imperfections in technique while more distant targets encourage a more instinctive type of shooting (point shooting)? I have noticed the same effect, BTW!
 
Did you change your finger position a little. That's all it takes. Too much or too little makes a difference for me on certain pistols.

I was wondering if that might be a contributing factor. Also the B8 is black of course, and I painted the torso white. Sights are Heinie ledge rear black serrated, and warren tactical fiberoptic front.

I don't think so... but I guess it's possible. I felt like I was shooting exactly the same.
 
your grip is changing, imo. figure out what grip gives those center hits and stick with it.

the difference is going to be very subtle.

luck,

If I read that correctly you also used different ammo? If so stop switching ammo.. If you want the smallest groups possible find the recipe or manufacture that your gun/barrel combo likes and stick with it.
 
Really don't think I'm changing anything. But I'll try again
a lot of glock shooters have this low-left problem (I've read it on the internet, so it must be true). suggest you use more trigger finger; all the way to the first knuckle if necessary.

luck,

All my Glocks shoot "left" (elevation is fine) with the rear sight centered. Every single one.

All my other guns shoot fine with the rear sight centered. As per the usual remedies, I tried changing my grip, finger placement, whatever, still shoots left.

Simple fix though. Move the rear sight right until its on. Works great. :D

Their 1 cent sights do leave little to be desired

The only Glock factory sight I had an issue with, was a Gen 1 "adjustable" they used to come in with. I clipped a door jamb going through it, and snapped the adjustable part off. What was left, still worked perfectly as a rear sight, and actually had better (for me) gaps on the sides of the front blade, due to the rear notch now being bigger.

Ive never had an issue shooting with the factory plastic sights, but I normally swap them out for either factory or Meprolight three dot night sights, as I prefer them to anything else.
 
Grip change with intensity of event. Shot anticipated expectation over ridden by grip.
Low me thinks indicates too tight of grip pulling the shot low or unconscious head raise.
Off center, push or pull on trgger instead of evenly straight squeeze.
If you shoot good on paper while just plinking you have to carry that proficiency in all situations.

Well since I switched calibers, yes, I switched Ammo. But with the 9mm barrel I shot low left at 10 yards and dead center at 18. Different targets though.
 
Low and left (for right handed shooters) is usually attributed to left hand tensing up and slight anticipation of the shot.

I know you are a good shooter, so that may not be it.

I know, for me, when I over think the trigger and shooting fundamentals, I tend to pull low left. When I relax and just shoot I have a much better showing.

Have you bench rested that thing?

Just a thought maybe not at all the problem, but I had a cracked frame that shot left. I moved sights and all but sent it in and that's what was found by Glock (gen2).

Thanks. I dont think thats the issue for me. Unless the 20 or so Glocks I have, all have cracked frames. :p

Yea, I dont know what it is, and it probably is me, but they all shoot well, and if I dilberately shoot groups, they shoot nice, tight groups. I just have to drift the sight over to the right to get them to shoot where Im looking. Weird thing is, they point just where Im looking when I point shoot them, so who knows. :)

Yeah but not for a while and I'm not great at bench rested shooting either. I can shoot a lot of other pistols center but this thing has a definite preference toward the left. At least on paper.
 
I know what I did to my Gen3 17 to get POI pretty much on top of POA. I put on Wilson Combat Vickers Elite F.O. front / blind battlesight rear sights, both matched at .245” high, which is taller than stock Glock sights, but per WC this is the standard height for Glock 9mm’s regardless of sight radius. WC does sell these in .230” high intended for 10mm and .45 ACP full size Glocks. I have the rear sight drifted right just about as far as it will go in the dovetail. I know that Dawson sells FO Glock fronts that are shorter than .230” if you need an offset to raise POI relative to the .245” tear sight, but I have not had to go this route,

I also have an APEX action enhancement trigger kit and a Grip Force Adapter installed, the APEX gives a nice rolling break of the trigger, and with a good tight support hand grip, I pretty much avoid the low / left trigger push that screws up a lot of Glock shooters. The GFA just improves the way the gun points for me, no doubt about it. And that’s it for the aftermarket stuff. Once I got used to the sights & trigger with a whole lot of practice, I could get good shot placement with various types of factory ammo. YMMV but this is what I have working for me with my Gen3 17.

I had the same problem with my M&P 2.0 Compact last week. I tightened my grip and that corrected it.

I got no business here. No Glocks.

But my habit is to shoot left with my CZ. An instructor just suggested I consider where the "V" between my thumb and fingers rests on the back of the grip when I draw. Just a slight rotation will pull the gun left when you fire.

Well I took corporal agarn's excellent suggestion and shot a couple of groups from a rest at 10 yards. First I shot the 40 caliber barrel and it made a nice tight group just above the front sight and maybe a tad right. Then I put the 9 mm barrel in, flipped over the target and shot a nice tight group directly above the front sight.

I was using a 6 o'clock hold for both of these groups. And a loose target grip so I could really manipulate a slow clean trigger break.

I was also closing my non dominant eye. So obviously it is something to do with my eyes, my grip, or my trigger control or a combination of all three. With the white background of the Target paper showing through the front sight gap it was much easier to see if I was favoring one side or the other. So maybe black sights on black targets is part of my problem.
 
My eyes are really starting to go, and Ive been finding more and more, that old age is creeping in and really starting to suck!

A while back, I put a set of Warren Tactical sights on my one Glock 17. Nice sights, perfect size/width, with good light on the sides of the front blade, but they are all black. They shoot great in bright light, on a high contrast target.

But, black sights on black or dark targets really suck! And they suck in lower light too.

If they could make a set like that with three tritium dots in them, it would be perfect. Without the dots, they are about useless, for anything but bullseye type target.

I started using the three dots sights back when they first came out and even before they were lit. I actually see the dots first, and use them for pretty much everything 15 yards and in. I dont start to look for or see a traditional sight picture until Im farther out.

With the old eyes going, its still doable shooting like that, but Im going to have to probably do something soon. I dont normally wear glasses for anything but reading smaller print, or in lower light and I dont like practicing diferently than how Im likely going to have to shoot, becasue I wont be wearing glasses when Ill likely need them.

Guess Ill have to figure this out somehow. But for now, I just give things a burst and load'em up. :D
 
I don't like 3 dot sights generall. Too much to look at. But they may help when my eyes get even worse
Naaa, once you get used to them, they are very fast, and give you both horizontal and vertical alignment, unlike some of the other set ups.

One other thing they are great for too, is using a suppressor without suppressor height sights. Its like using a red dot with the front cover closed, or one of the old OEG type sights. Strong eye sees the sights/alignment, weak eye sees the target, and your brain does the rest. :thumbup:
 
So maybe black sights on black targets is part of my problem.
I’ve experienced that.

I started out with fixed sight guns, and this matches my experience. I greatly prefer them to all black sights. But that may be my eyes.

My eyes are garbage.
