Glock 19 poa/poi question: Vickers sights and projectile weight

Front sight too tall.
7yds shouldn't matter unless the front height has changed.
That's the only time I've delt with it.

Let someone else familiar with Glocks shoot it. If you think the windage needs to be messed with beyond centering, chances are you are pushing the shots down.

I've never had a Glock, or mounted sights on a Glock that needed the rear sight offset from center. And every single Glock I have ever shot, where the owner claimed they need to adjust the rear sight, shot dead center with a centered rear sight.

^^agreed. Mechanically zeroed sights and a good trigger press delivers 100%.

.215 for front sight on a G19.

.215 for front sight on a G19.

That depends entirely on the rear sight height.

Just an old reminder about adjusting iron sights for anyone that peruses this thread.
FORS
Front Opposite Rear Same
*regarding which way to move the sight to change POI. [emoji106]

I'm familiar with glocks. I've had a 27 for over 10 years and shot idpa with it for two years.

I put new front and rear sights on it, that's why I thought it might need windage, but it's dead on centerline, right where I pressed it.

I'm not pushing the shots. When I do, it's down and left, not straight down. I just had a two day class with LAVickers last month and am comfortable my basics are good. I was careful to implement the fundamentals.

It's definately shooting low, and in googling it, I find posts that the 19s shoot a bit low with the 9mm sight, and that people find them ammo sensitive in terms of height, with heavier bullets hitting poa.

Looking for conformation or dissimilar experience.

Seems like your going down a rabbit hole.

Not at all. Different manufacturers recommend different front sight heights based on the height of the rear sights they sell.

Most manufactures that recommend a .215 front sell it with a .250 rear.

After doing some research, the Vickers is a .255 rear and recommending a .245 for small frame Glocks does seem a little odd and is entirely the reason you are shooting low. Based on my experience, the .230 would be a better fit.

Don't some manufacturers use a different hold as well?
6 o'clock vs covering the poa vs 1/2 cover of poa etc..
Different poa & poi using common @ 6 hold.

In general, heavier bullets shoot higher.
This is because heavier bullets usually move slower and the gun spends more time in recoil (muzzle climbing from where you were aiming when you fired) and therefore the bullets are pointed higher when they leave the barrel.
You can shoot different weight bullets at the same velocity and you will usually get the same point of impact at short (handgun) ranges.

You actually adjust a pistol's sights to account for this muzzle rise which occurs while the bullet is in the barrel.
A pistol usually has the bore pointed down from the aiming point so that the barrel will be pointed at the desired aiming point when the bullet leaves the barrel.
This is why bullet weight traditionally effects the point of impact with the same point of aim.

Thanks Randall, that all makes sense.

What fixed front sight height would you recommend for a stock G19 if you're shooting 115-147gr 9mm and want POA/POI at 25yrds or less?
