Well...these aren't my "fantasy picks," but they are the weapons I might pick up in the next couple of years, in order from most to least wanted:
1) 1911 = any good used Colt, Kimber, Springfield, etc. in the classic 5" length, preferably with 3-dot nitesights and a long trigger. I still miss my stolen Kimber 3". Now I think full length makes more sense than snubby.
2) A good J-frame snubby in .38 or .357. I'd prefer a model with a concealed hammer. .38 would be fine, .357 is just gravy. I have little urge to shoot .357 in a J-frame--YET! These guns carry very well for me.
3) A GP-100 in 6" with full length underlug. I'm gonna have to give my "loaner" to my stepdaughter one of these days, and I want one of my own. A nice shooter/handload development tool.
4) A CZ-75 in 9mm. These just feel very nice in my hand.
and....a good Buckmark or or DA Smith .22 -- can't really fit this into the above picks, I'm just keeping my eyes peeled for a good deal.
I'm sure this list won't "survive contact with the enemy," but I am going to try to keep my caliber list down to want I currently can handload (.38/.357,
9x19 and .45 ACP). Someday, I might add a heavy duty (.44 Magnum and up on the power scale) revolver that also fits in a nice carbine.
