Have heard that the Hogue slip on grip can make a fullsize HK USP less "boxy". I love my compact USP grip (it's thinner), but I was thinking of putting the Hogue slip on onto my fullsize USP.
Would this make it even fatter, though? It has the palm swells on the side. And, when I added Hogue grips to my Beretta 92FS last year, it made the gun too fat. I ended up taking them off.
Didn't wanna waste the money on the hogue if it made the gun feel even fatter.
