Guys I'm kind of new to the H&Ks. My question is can I use full size USP sights on a compact USP? I really like the custom combat novak fiber optic sights and would like to put a pair on my .45 compact.
I apologize for the short answer. With the factory sights, the rear sights seem indifferent. The front sight, however, is 6.2mm on the compact, and 6.8mm on the full-size. The dovetail looks exactly same and the clearance is the same for both. You'd just have to adjust for the different POI/POA.
The Novak is different. While the front may seem to fit, the rear will stick out about 1/3 inch on the compact.
