...what would it be?
I'll start it off with a few popular calibers:
.22LR - Ruger SR22
.380ACP - Walther PPK
.38 - S&W J-frame
9mm - Beretta 92A1 or Glock 19 (9mm is the hardest one for me to decide)
.40S&W - HK USP (Tactical)
.45ACP - 1911
Sig 226 should be on the list too. 9mm is the only one I would have a hard time choosing just 1 gun.
