Hey yall truglo tfo, hiviz, and trigicons shoot high at 25yards... about5 inches high.any good fiber optic sifhts tgat shoot poa?
TruGlo (and probably the others) make two different heights for Glocks. One is for the smaller frame models (17, 19, etc) and the other is for the large framed Glock 20, 21, etc. If you are shooting high, you could try the rear sight intended for the smaller frames. It is slightly lower & will lower the point of impact.
If it shoots on center, but consistently high, I do not recommend changing them, solely because of that. That POA may change with different ammo. Until you know how it shoots with all possible ammo you might use, you may be causing more issues than curing. Unless you are shooting competitive, on center and 5" high is no issue. Compensate, if you must, or use adjustable sights.
I found that shooting high with all my 10mm glocks. I now buy adjustable sights. Or order tall front sights to offset it.
