Sights And Point Of Aim / Impact

[dohboy]

I'm fairly new to the forum so if this topic has been already discussed please point me to the right forum/link and accept my apology.

I have installed different sight combos (Heinie, Heinie Straight 8, and Sevigny Comp) on my G22 and G35 and both guns shoot high (aim at middle A zone at 25 yards and POI is high A zone or even the C zone). I've used handloads, factory loads (UMC, CCI, Gold Dot, Golden Saber, etc) with the same results in my .40s. The only way I've been able to correct my POI was install a taller front sight (Heinie .250") versus the standard height .215" or .225" that came with the sight sets. With the .250" FS, my POI = my POA at 25 yards and with the above listed ammo.

Is anyone else out there experiencing shooting high with their G22 or G35 versus the 9mm Glocks? If so, what could be the explaination for the .40 Glocks shooting high versus the 9mm Glock (at least for me)? Please, before someone mentions improving your aiming and marksmanship skills, my G17 and G34 with aftermarket sights (same brands) are dead on with the OEM aftermarket front sights. Thank you in advance for you ideas and suggestions.

Dohboy-

Unfortunately, ever gun is different. Some of the poa/poi issue is how the bbl. locks up in the gun. I know that a factory bbl. gives me a different poi compared to my KKM bbl. You need to tune your load and front sight height for the poa/poi you want. I run two G22's for IPSC, IDPA and MultiGun. I use a Heinie slant pro rear and a .90 wide, .215 tall front sight from Custom Glock for must of my shooting. (If shooting IDPA with low light I put on a pair of TruGlo TFO sights, but I don't shoot a lot of IDPA). Both the above guns shoot slightly high as well. However, I actually like my poi slightly above the top of my front sight as this allows me to see more of the target.....I can float steel plates and head shots, etc.

I recommend you find a load that shoots well out of your gun. Then spend some time on the range learning where your gun's poi is at different distances. Again, a higher poi does not have to be a bad thing......... As long as you know where to hold to achieve the disired poi at any give disantce, you will be good to go. Hope this helped.

I can't say that I've experienced any difference between the 9mm and the 40.

I might suggest gripping the 40's a bit more aggressively...with the off hand. (Assuming the shooter is using some variation of the thumbs froward iso grip and stance.)

Precisely why all of my competition guns have adjustable sights on them. The Ameriglo target sights have a fantastic sight picture, as good as a Bo-mar to me.

I have a G35 (fixed sights) which I shoot 180-gr .40 from and also 115-gr 9mm from using an alternate barrel. I don't notice much difference in POI between them.
