If you could have any 1 handgun in each caliber...

[RVTECH]

45acp = German Luger

Good choice but I believe the only ONE known to exist sold a couple years ago.

So, I've been on a shopping spree to build a collection according to my list. I bought, sold and traded and here is where my list stands:

.22LR - Ruger SR22 Threaded Barrel
9mm - Glock 19 Gen 4 (can't believe I found one yesterday)
9mm - Sig P226 Elite Scorpion Threaded Barrel
.40S&W - HK USP Tactical
.45ACP - Kimber Eclipse Target II
.45ACP - Springfield XDs (currently, my only carry gun)

My next purchase is a PPK Stainless and then I'm done for a while.

I hate to be a spoiler, but if you have a 38SPL, then you can not have a 357 because that would give you 2 pistols in 38SPL. Nor could you have a 44 mag and a 44 spl. for the same reason.
BUT thanks for playing

It says .357 Magnum and .44 Magnum on the barrel, so I get to have two more revolvers than you.

.22LR - Ruger Mk II 6-7/8" heavy tapered barrel
.30 Carbine Ruger Blackhawk
.32 Auto Walther PPK
.327 Ruger GP 100
.380 Auto Browning BDA
.38 SPL Taurus 82
.357 S&W 686+ 6"
9mm CZ 75 B (I'd take my G26 over my G19)
.40 S&W ???? I've got a Glock 23 but think I'd want something heavier, M&P, CZ or Beretta
.45 ACP SR1911 is the best I've got - it does just fine
.45 Colt Ruger Stainless Vaquero
