Considering adding the above sights to my USP9c. I have had several sets of Heinie Straight Eights and am familiar with them. Question is if this combo actually regulates with 115 or 124gr, and at what distance? Heinie's seem to prefer a certain load. Also any pics of how high they sit on a USP9C could be helpful. They sit high on my .45c and cause POI issues beyond 25 yds for me with 230 gr.
