I ordered the 4 plastic OEM sights of the different heights that Glock sells. Figured that one of those should be the correct one and should be better then the adjustable one that came on the 44.

This is a good idea for those who like black sights. I am probably one of the few shooters who likes the Glock sight picture. The biggest advantages for me are the certainty with which the fixed sights will maintain adjustment once installed as well as the plastic construction to avoid damaging the plastic dovetails.
OK back to the range today for some more "sighting" activities. Now, out to 15 yards, shots were consistently above POA by as much as 3 or 4 inches. But, there is no more adjustment available in the rear sight so will have to live with this. It is well centered at 5 and 7 yards and that is where I will do most shooting. I guess I could replace the front sight to get some more adjustment room but looks to me like there is no where that 5, 7 and 15 yards are all going to shoot POI at the same POA. Seems that this .22 definitely gains altitude at least out to 15 yards. I read somewhere that Glock sights these to be POA = POI at 25 yards so it must start dropping past 15 yards.
Windage sighting was very well centered at 15 yards just as it was at the 5 and 7 yard targets. Seems to be well aligned on that axis.
Something's wrong. A difference of 3 or 4 inches in POI moving from 7 to 15 yards doesn't make sense.
Here's the CCI standard velocity trajectory plot when sighted in at 100 yards:
That's probably a rifle barrel, so a pistol will be a bit steeper, but still much less than what you're seeing.
Yes, I see what you are saying. So when I go back to the range next week, I will shoot some more at 7 and 15 yards and again see what kind of variation I get. I guess looking at that chart that it should be much closer from 7 to 15 yards. So, I will check it again and be more precise on measuring the difference.
Thanks for that help and information.
If I understand correctly, you are using a 6:00 hold to hit at 7 yards? This means that the trajectory of the bullet crosses the line from the sights to the target before that 7 yard point. I would expect that bullet to continue rising at least out to 25 yards, perhaps dropping a bit before reaching 50 yards. So, your 15 yard results do not surprise me.
When I first shot my G44, I was convinced that I did not need to adjust the sights from the factory setting, but my most recent outing caused me to question that finding. Reports in this thread of the sights shifting due to slide reciprocation have made me curious. These sights were designed primarily to enable the G26 and G27 to score enough sporting purposes points to permit importation, and were never highly regarded.
