I agree with the others about buying what fits, what you shoot best, and what you like.
I've come full circle after having a cabinet full of Walthers, trading or selling several of them off, buying from the Sig and HK line and eventually selling them off and returning to an all Walther gun cabinet.
I've had the Tactical, the USP9, and the USP45. All were excellent handguns and never gave me any problems. They were all 100% reliable. Unfortunately, as much as I liked them, I did not shoot them well because their grip design did not fit my hand. My only other beef was with the trigger system, except on the Tactical model.
The SIG-Sauer line was also another excellent product of Germany. Now U.S./German built. I've owned the P220, P225, P228, and. I wasn't able to do much better with this line either except for the P220 and P225. I also do not care for a stamped and rolled sheet metal slide with a pinned breech block.
The P99, P5 (P1/.38/4 etc), and P88 fit my hand much better than the USP or SIG series ever did, and the targets show that. I'm glad they do, because as I suspected, the Walther line is the one I really liked to begin with.
Oh, and by the way, many folks at HK Pro do not think that any one else builds firearms. And I used to think that I was a gun snob. I can't hold a candle to most of those folks.
