Why do I keep shooting left?

Go back to gripping it like you did when you first got it. The "proper grip" is evidently not the proper grip for you.

It means that you are squeezing all the fingers not just the trigger finger (I assume you are right handed). This will move the gun left as you fire. The easy cure is to get a very tight grip, sort of a death grip on the gun prior to firing. If that cures it, then you know you were milking it.


The chart you were looking at may have been for left handed shooters.

Id guess you are putting the joint of your finger on the trigger. The pad of your shooting finger should be centered on the trigger

I have never seen that graph. Thanks Beeenbag!

You are anticipating the shot and subconsciously tightening your grip before every shot.
Its probably not your trigger pull, but rather your hand squeeze. Also try not to take
a python like death grip, firm but not over firm. When you get it right you will feel the Zen

You could also be pulling with your off hand especially with a locked arm/shoulder.
like others have suggested, just work with a comfortable grip to get accurate first and follow up shots, and what works for one, may need adjustments to work with your body.

im just finishing up an advanced firearms class, and i had the same problem as i was going through basic firearms.

i was consistently shooting left and it just would not change no matter where i put my trigger finger. the instructor told me that i was "milking" the trigger, meaning that as i squeezed my trigger finger, i was also squeezing the gun with just the fingertips of my strong hand.

try taking a very firm grip with your strong hand and not much more than a firm handshake with your left. dont squeeze untill your hand trembles, but get a real good hold on it. after this all my shots moved right on over to the center of the target.

hope this works for you too!

Hi Sky,
I posted this a while back. It's a graph at ShooterReady.net with "Causes" and "Solutions" for each area on the graph.

Hope it helps.

I have only been shooting for 5 months but here is what happenend to me. I started out good than as I started to worry about things like grip, things went down hill. You said at 1st your shooting was spot on. Your thinking to much. Take the gun point it at the target and pull the trigger. Keep it simple, when you don't things can go bad. You say you like the gun for CCW. If the time ever comes to use it as a tool are you going to sit there and think about grip and trigger pull? No your going to grab the gun, point at the target and pull the trigger.
There's my two cents. Like I said I am new at this and just trying to help.

you got some good responses here...to which I'll only add what the one fellow touched on "propper grip" is ultimately what works for you the shooter...my wife's is a little different than what I taught her (standard and modified weaver) but she found one that is a)repeatable and consistent for her and b) feels natural for her (which probably explains a don't be afraid to deviate from what you see in class or on videos a little if you need to find what works for you. As long as it's safe of course. And those of us with unusually large or small hands depending on the gun may not use "the exact middle" of the finger pad. That's a good place to start with a new gun...but some models I use the inside half of the middle...I go by the angle my finger presses at...you want it coming straihght back....so where-ever it fits that gun and does that may be "the sweet spot" for you.

Most guns and most shooters that's the middle of the pad...mine often is off a little from that...I have to shoot some guns a little to find that spot. I also have to work on my grip with some new guns...my new sig 2022 I had to find both. Now it shoots great! It started shooting low and sometimes left or right a bit as I expiremented with finger position.

Grip and too little finger on the trigger can make a handgun shoot left but there are other reasons.

The agency I worked for bought Glock 19s in the late 90s. When we conducted familiarzation and qualification probably 70-80% of them were shooting left out of the box. It always isn't the shooter. We're talking maybe 600 guns here not a small sampling. Rear sight adjustment to the right fixed them all.

Those targets are just a general guide. Just because you are shooting due left and not left and down doesn't mean you aren't milking the grip.

This happens to me when I get "lazy."

Try this:

1. Find a good, comfortable grip with the following characteristics: Make sure you are not tea-cupping. Your off hand's fingers should be wrapped around the fingers of your strong hand with your off-hand index finger under the trigger gaurd. Try to make sure as much of the palm of your off hand as possible is in contact with the off side of the weapon's grip. Your off hand thumb should be over the top of your strong hand thumb and laid along the side of the frame.

2. Take a good Isoscelese stance. Make sure your knees are slightly flexed and your torso is leaning slightly forward.

3. Reach forward with both arms until your elbows lock. Push toward the target with your strong hand. Push back against your strong hand with your off hand. Push as hard as you can with both hands.

4. Place your trigger finger on the trigger up to the distal joint (first joint) so that the joint contacts the strong side of the trigger.

5. Squeeze as hard as you can with both hands.

6. Line up your sights and squeeze the trigger.

Obviously, pushing as hard as you can and squeezing as hard as you can is not a sustainable shooting position. However, doing so for a short period of time will help eliminate issues like milking and pulling with the off hand.

For those that aren't aware or don't know, the isosceles stance and weaver stance are both outlined here quite clearly. There is also a great deal more information on the site related to firearms fundamentals.

Isosceles stance:

Both arms are extended outward, with the elbows at their natural extension. This puts the axis of recoil more or less along the centerline of the body. The stance is so named because a path drawn along your extended arms and connecting your shoulders forms an isosceles triangle.

I'd say that it's your grip style or milking the grips or whatever as well but for the fact that you say you're getting great groups with your other guns. That sort of shoots the idea that your style is off right in the foot. Having said this I can't suggest anything to help you out other than perhaps that the gun just plain ol' doesn't fit you well. If you're using the same grip on the other guns as the Glock then it SHOULD shoot for you just as well as the others. And for the sake of consistency the last thing you want to do is start having to learn a different grip hold for any single gun that compromises the others.

And just in case you'd like to look into some basics to see if maybe you've "modified" your grip too far from the correct foundation here's two online freebies that I've found to be the best.

An excellent description of the two handed thumbs forward semi auto pistol grip. This write up ties in well with the next link.
