Hello,
I am from France for things to be clear at first

We can't just stack up as many guns as we would like to.
My dad wants to sell his USP 45 Tactical and I have already one myself. His one has only 500 rounds through it, it's a BE like new and I have myself a KI that I got already well used with a trigger pull even nicer than the one I had on my Custom Sport.
Are there any differences over the years for the match trigger itself and if I were to keep the BE one, would the trigger over the time get as nice as the one I currently have ?
Also, it's funny, the KI one has an engraved HK sign on the slide and the finish is mat while the BE has a laser engraved HK sign and the finish is more glossy.
It's just to know which one is going to be sold. I've never had a better handgun than this one, I hit a gong 12 times on 12 at 100 meters...
