Glock-17 POA/POI

[bigtattoo79]

My Glock-17 is shooting high left and I will say it could be me doing something worng. I am starting to aim low right to get my shots on target but started thinking this may be a bad habit. Should I put a taller sight on to fix it?

They typically shoot point off aim.. What is the range you're shooting, also are they factory sights?

Do you know the height of your front and rear sights. If you are doing everything right you either need a taller front or lower rear. How high are you shooting at what distance?

Much more then often then not it's the shooter. Buying new sights will only fix the cash in your pocket problem.

Not sure of the height of the rear but the front is the .215 that the rear calls for http://www.dawsonprecision.com/ProductDetail.jsp?LISTID=800008E5-1212764700 .
About 4" high at 20 yards. In the chart below my shot would be in the "P" in the "P"ushing Anticipating Recoil.

20-25 Yards. Not Factory sights http://www.dawsonprecision.com/ProductDetail.jsp?LISTID=800008E5-1212764700 .

The .245 front would be about right for you.

High and left is a rare shooter-induced instance in the event of someone who is experienced and holding a feasible group. I've seen you shoot, so I find it unlikely.

That said-- LEFT push with a Glock is common and repeatable by even expert shooters. That part may be you, but I suspect the "high" is mechanical.

The Warren/Sevigny sets are sold gun-specific, so is it possible you snagged the wrong set? IIRC, they have them for the 19/17 as a pair, then the 34 and 26 individually.

The KKM could also have radically altered POI, and different bullet weights/profiles show more shifts at distance in those match barrels than in the factories.

I'd bench it across the next couple of weeks and make sure it's still printing high. If you can get anyone else even remotely decent to shoot it, things like 4" high @20 will be obvious and you can fix the issue from there.

Oh, and that Bullseye Shooting Correction Chart should be cast into the pits of Hell with whoever posted it in every public shooting range on the planet.

I will also add that if I shoot it off hand its still high left. You got me thinking about the KKM now.

I have a G35 with a KKM and the same rear sight (comp model). I needed a .235 front to hit POA, though I ended up using a .225 since I tend to shoot a little low when firing rapidly. The .215 Warren front is supposed to work with the G17/22, and the .245 is supposed to be right for the G34/35. I'm glad Dawson has sights in .010 increments, because I needed something in the middle.

 

[Sin-ster]

Just to clarify, the KKM may be the cause but there would be nothing wrong/out of the ordinary about it.

Good info. I did order a new .215 and .225 today. I am using a very thin front right now and thinking my shooting left may be from that big gap on each side of the post messing with my eyes.

I will be so mad if its been the KKM all along.

I like this one a bit better. Awerbuck would kill me with his stare for reposting this that has him attributed to it, but here it is. I can see where he definitely influenced this one though. I distinctly remember many of these when attending his class.

I tend to shoot my Glock to the left a little as well. I've corrected it, but it was induced by me milking the gun. For the pdf linked, that would be number 5 for the 9 o'clock portion. Many people tend to pull the Glock a little to left (right for southpaws). And, like Sin said, experienced shooters do/have done it as well.

Shooting left with a glock is caused by death gripping it with the strong hand. You should be holding the gun as you would hold a raw egg without breaking it. The grip strength should come from your support hand.

A .225 will only lower your POI approximately 1.5" when compared to the .215 front sight.

This right here was / is the cause of my left, low left shooting.

How often have you seen a Glock need a taller front sight because of the gun and not the shooter?
