I just bought a new USP 40 and turned it into a combat competition. I.m very impressed with the gun overall especially the Novak sights. As I purchased my hk inventory I've been installing mepro night sights in them. It's crazy with the amount of sight options there are for guns. These Novak sights as you all know are blacked out in the back with the fiber optic front - what a combination! It just makes me wonder if I had done some more research and gotten maybe the Heinee sights with the blacked out rear or Novak sights for the rest of my guns. The target acquisition is fast. The only night sights I would have needed would be for my cc gun (p2000sk). The rest of the guns are basically range guns. I tell you, these novaks are just night and day with the mepros no pun intended.
