    Glock Gen 4 Shooting High

    I bought a new Glock 19 gen 4 yesterday. It is shooting about 4 inches high at 7 to 25 yards. I shot about 150 rounds yesterday and it didn't get much better. The pistol is very accurate with a 4.5 pound trigger. My Glock 17 shoots about 2 inches high with Meprolight night sights but 4 inches is a little to much to deal with. Is changing the sights the best option? I hate the factory Glock sights.

    Not trying to insult you or anything, but have you let another shooter try it out? Every Glock I've ever come across is dead nuts on from the factory. Even the best shooters go through marksmanship deficiencies sometimes without even knowing it.

    I haven't let another shooter try it out yet but I will do that today. A friend of mine also has a Glock 19 that shoots high. You have to use a entire front post hold. I mean you have to be looking at the slide to hit the center of your target. I changed the back strap out last night and put one on there for larger hands. It makes it feel about like the gen 3. I going to put about another 150 rounds though it today. It it doesn't get better I may trade it back in. It looks like it is not going to work for what I bought it for anyway. I was wanting a conceal carry gun but it is going to be much to big. I'm not giving up on it yet though.

    Keep working with it for sure, and definitely let someone else run a group through it to check. As for carry, a G19 isn't the easiest but is what I carry all the time and my favorite for CC.

    Are you lining up the dots or the top of the blade? I don't understand your look at the slide comment.

    The POI won't change based on the number of rounds you fire through the pistol.
    And if you have to 'look at the slide' below the front sight post in order to hit the target then the pistol is shooting low, not high.
    Because your other Glock has the same 'problem', if the POI is that low then it's probably not the gun.
    Show us a target with a five-shot group at 15 yards.

    The rear sight can be switched out with sights of different heights, but I am not sure sights are the problem.
    Here to help when I can and learn when I can't.

    LOL! I didn't stop to consider that he might be posting from Australia. That would explain it.

    Could this be an indirect cause of the accuracy issue?

    My Gen 4 Glock 19 also shoots very high. So I threw some night sights on it. They were apparently the same ratio to each other, and it continued to shoot high about 4 inches at that range. I was going to replace with either a taller front sight or shorter rear, but, I took delivery of my new KKM Precision threaded barrel. now it shoots exactly Point Of Aim, and actually tightened up the groups a lot.

    My Glock shot high in Breckenridge, Colorado. But, then again, that whole town is high.

    are you using the top of the front sight as your intended POI or covering your intended point of impact with the front sight....the "shoot the dot" technique... they way you would a sig?

    What I mean by my earlier comment is I was taking the front sight post and making it flush with the rear sight. I have found in order to hit my target I must put the black part of the front sight under the dot not just the dot on top of the rear sight post. When I look through my sights the front sight post is taller than the rear. I must combine this with a 6 o'clock hold to hit the center of the target.

    I hope this helps. This is difficult to explain without a picture.

    Graham, you are right. I left the post above this one so you all can see what I was doing wrong. I just had it backwards. I just now went out and tried what you said about the sight picture and I was wrong. I changed my hold to a front sight lower than the rear by about half. I can only see the upper part of the dot on my front sight now and have eliminated the 6 o'clock hold. I am not going to post any groups because I don't feel the need to embarrass my self any more today.

    Thanks for clearing things up.

    What would be truly embarrassing is to continue to shoot high due to incorrect technique and not asking the question. Now you are good to go and we were entertained. Its another Snipershide win-win!

    I just saw your picture of how you are lining things up. Its not the gun/sights. Glocks have a lower bore axis and with that being the case, you have to bring your head "down on the gun". Lots of people have this problem with glocks, especially if they are used to shooting something that has a higher bore axis, such as a 1911, sig, HK, etc. If you don't bring your head down on the sights so that when you look at your front sight post, the back 2 dots or the rear outline is even with the front post, you will hit high. In your case, what you should have is the front post exactly center with the rear outline when you are down on the gun. If you do that, the gun will shoot dead nuts every time, provided you are doing everything else right. When I shoot my glocks, my nose is even with the rear of the slide and my eyes are looking straight through the sights. Everything needs to be centered. Its going to take some practice from the holster to get consistent. Like I said, this is a pretty common problem for a lot of people when they switch over to glocks and aren't used to a gun with a lower bore axis. Hope this doesn't confuse you. If we lived closer and were on a range, I could help you correct this problem in like 2 minutes. Its an easy fix.

    I'm confused. Especially as to how this special Glock problem of a lower bore axis requires the shooter's nose to be even with the rear of the slide in order to use the sights properly. If you didn't simply make-up what you posted then please give us the source of the information.

    Because if what you said is true, then flash point and point of focus sight pictures do not work. And I'm especially confused as to how (DT/SR) x AE does not equal POI. Because with a standard open-sight configuration of a post front sight and a notch rear sight, a proper sight picture consists of aligning the front and rear sights so that the top of the front sight post is level with the top of the rear sight notch and the sides of the front sight are an equal distance from the sides of the rear sight notch. What do the bore axis and your nose have to do with anything? I can get the same POI when holding my Glock upside down.

    I was afraid I wasn't explaining myself clearly. This topic is really hard to explain without the use of pictures or while shooting on a range. I guess what I'm trying to say is due to the grip angle on Glocks compared to some other guns such as 1911's, Sigs, HK's, XD, etc, you have to bring your down lower because the grip angle is different on the glocks. When I shoot my Glocks after using my 1911's, Sigs, etc, I tend to have the same sight alignment as the picture referenced above. I have to make a conscious effort to bring my head down on the sights or I will hit high. My natural point of aim is dead nuts with the 1911, Sigs, etc, but it isn't with the glocks without some effort. I'm sure you and I are on the same page Graham...I'm just not explaining myself very well. Sorry for the confusion.

    Do you mean that, because the grip angle on a Glock is greater than that of a 1911, the shooter has to bend the wrist of the shooting hand further forward in order to properly align the sights?

    I don't bend my wrists with my Glocks because I don't want to start any bad habits when shooting other pistols, besides, the accuracy starts sucking when shooting fast. In order to make the easiest correction, its easier to just bring your head down on the gun. It works for me. The main point is attempt to compensate for the engineering differences between the pistols to find your natural point of aim. The Sigs, 1911's, etc are closer to my natural point of aim. I don't have to bring my head down, bend wrists or anything with the 1911's, but I do with the Glocks. Btw, IMHO, bending your wrists when trying to shoot a Glock or any other pistol is a bad idea. It really dicks up your accuracy when you shoot fast. Wrists need to be locked out, or you'll be all over the damn place on the target. Its easier to bring the head down on the gun and lock your wrists out.

    You're confusing me again:

    One locks the wrists by bending them forward and pointing the thumbs. Bringing the head down is one method by which to aid in locking the elbows.

    Ok, we are on the same page. I'm basically advocating thumbs forward approach. Gripping the pistol is the same regardless of what it is. I just find myself bringing my head down lower on the glocks because the bore axis is lower. With the Sigs, 1911's, etc, grip is the same (thumbs forward, wrists locked out), but the slide sits higher on the 1911's, Sigs, HKs so I don't have to move my head as much to find my natural POA. Depending on what the situation is, I will just reference the sights and will be indexing with my thumbs on the target. It works and its very fast.
