Best upgrade for a well-used hk usp - Trijicon Bright & Tough H&K 3 Dot USP Night Sights

I ordered this set because I got a great deal on a used USP from a pawn shop. I estimate 10K rounds on this gun, and it still runs like a top, but it was bone stock. The HK factory sights are good, but I do believe in these sights, and all my other pistols have Trijicon Bright-N-Tough sights, so this choice was easy. They installed easy (I have my own sight pusher tool) and shoot exactly to POA (remember HK's have a "cover up what you want to shoot" sight picture) once I did a tiny drift adjustment. No marks on the rear sight (put a piece of electrical tape on the punch and sight) so I know it's tough. The Optics Planet product is new, and very bright- not ancient and dim, old warehouse stock. I can also confirm it's official Trijicon and not a Chinese counterfeit. I got the 3 greens setup and I can easily spot my gun in a dark room the sights are so bright!
