Point of aim

[2IDdoc]

Hey guys,

I've had a G19 and G17 for some time now, and run many K of rounds down the tubes through many classes and so on. When I first bought these pistols I put new Trijicon sights on the front post only.

They have always shot high. I read somewhere a long tmie ago that you were supposed to lollipop the sight picture, so that's what I've always done. From 25 yards on in I can get my hits fairly quickly. Lately I've been toying around shooting at longer ranges. And it seems that the farther out I go, the more exaggerated the distance between where the front sight is lined up and where I want the bullet to go becomes. I have to hold fairly low at long ranges and at even not so long ranges like 50 yards.

This is irritating because I don't really have to hold over with my 1911 at 50. With my Glock its a guessing game as to how far low I hold my sights. I don't like this at all.

So my question is, how do I get a military style sight picture with my Glocks, where I aim center of mass to hit center of mass? This lollipop stuff is getting old.

I've found that under stress I revert back to aiming center of mass. This kind of scares me considering how I carry my G19 ever day and I have to aim low to use it.

Sounds to me like you goofed when you changed the front sight only. My guess is that the Trijicon front sight is lower (shorter) than the original Glock front sight. If this is true, then you will need to replace the rear sight with a proper height unit to match the front sight.

I agree on the probable mismatch. If you like the Glock rear sight, they do make several different heights to adjust POA/POI. Contact your local Glock dealer or armorer, or Glock Inc, and try the next lowest sight.

Although, at most realistic pistol distances, it should not make a huge difference. How far off is it shooting, at what distance? For personal defense, a few extra inches of elevation at 25 yards won't cause a hit to become a miss.

"Lollipop the sight".....like holding the front sight up high above the top of the rear sight?

You should align your sights just like any other normal iron type sights are aligned.....the top of the front sight should be level with the top of the rear sight and evenly spaced in the middle of the notch. Like this:

Glock makes four different rear sights so you can sight in the gun the way you want it.

A six o'clock hold gives you a specific repeatable point of aim and gives you the best chance of shooting a good tight group, which makes it easier to sight in your gun.

A gun sighted to hit point of aim would put it's shots on the target right at the top center of the front sight, like this:

A gun sighted in such a manor will allow the shooter to hold 'center' and hit such things as:

An eight inch steel plate at 11 yards,

A humanoid target up close,

A humanoid target far away,

Or a pop can (soda can if you're not a yankee :)) at 50 yards,

I'll check on some different rear sights here as soon as I can. I didn't realize Glock made four different sizes.

There really isn't much of a problem out to 25 yards. It just shoots a little high. At longer distances like 50 yards it starts to get very exaggerated. It shoots higher than my 1911 or my G17, or my AA .22 conversion slide.

When I say I'm lolypoping the target I mean that I am using a 6 o'clock hold on the target. My sights are lined up properly. I'm not a novice shooter, though I may get a term confused every now and then. ;)

I don't like the 6O'clock hold, I like center of mass. I blame the Army for this mental condition.

Thanks for he advice all. :)
