Oh, I totally get it. Especially as a person that love analysis...'okay, here's a 9mm Glock in three sizes...here's .40 in three sizes...let's compare and contrast.'
That just gets old quickly, is all. I wasn't trying to mock his collection of guns, just pointing out that none of them were truly 'collectible' in the typical sense. More of a Pokemon 'gotta catch em all' thing going on there.
OP, if you are avoiding older guns because you think the modern stuff is simply 'better' from an engineering, design, or build quality kind of standpoint...I would say give some old cheap stuff a try. You obviously have a bit o' disposable income, and it's hard to lose money on guns, anyhow...so buy something that seems wacky and contrary to your tastes. You might end up liking it. Here are some random suggestions for stuff that is pretty cheap and plentiful:
An old Colt wheelgun. Any of them. They are very impressive pieces of engineering...I've not shot any newer revolvers that have the same feel of precise function.

I like those the best, because it's an affordable, high-quality, typically post-war gun. But it still has that cowboy SAA feel. The 'Police Positive,' often incorrectly called a 'Police Special,' would be the other common ex-cop revolver.
You've got a proper metal-framed CZ. Otherwise I'd recommend some guns in that lineage. Say you wanted another CZ design, though, and you wanna go for more cool and unusual...look for a .41AE Jericho.
For more Rusky and/or East European action, try a CZ-83 or a Makarov. If there was a Russian James Bond, he'd totally carry a CZ-83.
Speaking of James Bond- any interest in suppressors? I fear recommending them, as it kinda feel like offering meth to a coke addict. Or something. You may end up liking them and getting into a serious suppressor habit, is what I mean. :awe:
I don't see any threaded barrels in your collection, but I'd start with a .45ACP, regardless. Easiest to suppress. I think your full-size USP can be 'tacticalized' with just a barrel swap. Should still cycle fine.
