Add me to the list brother, my favorite pistol, and most accurate, and most fun to shoot is my HK USP 40. At 25 feet I shoot the little pins off that hold the target to the cardboard, 2 shots max. I can't do that with my 226 in 9mm, and I certainly can't do it with my G19. I can, but takes more shots to accomplish.
I have read that 40 is one of the most accurate cartridges out there, and I tend to think it's true. Never had so much fun shooting until I bought this caliber
