So I have two home builds. OK, kill me. One is a G19 with a KKM barrel and it just rips up the bull at 50 feet. 115gr and 124gr Blazer Brass The other is a G17 with a KKM barrel as well. I like to shoot 115gr Blazer Brass (inexpensive) and the G17 is way low left with this. My front sight is to tall and I have a shorter one en route. But this barrel will never like 115gr Blazer Brass. 124gr I can probably make work. It's just strange how the G19 kicks a$$ on the G17. I wonder if I should send that barrel back or just adjust to it ?
