The guys are right, if you like the deal, then it was a good trade. Personally, I prefer H&K, myself. I sold my Glock 23 to a good friend who needed a concelable gun for teraining at Gunsite Raven. I don't miss the 23 or have seller's remorse. As mentioned, I don't care for the grip of a Glock either. I could never get used to the trigger, although mine shot very tight groups. In the final analysis, I sold the gun because I never warmed to it, and that's not a sin.
I love my H&K USP SW .40, that's the bottom line.
As a matter of prcaticality, I do know that Gaston Glock took an early Model 17 and poured 100,000 rounds through it and then measured the tolerances. Sure, it showed wear, but the gun was safe to shoot and the group size had increased only moderately. That is incredible engineering.
