I refrained from voting because my collection is really a combination of the two. I have one of pretty much every category (pump & sxs shotgun, .22 rifles and pistol, revolver, automatic, BP handgun, high powered rifles, intermediate powered auto rifles, ultra-compact handgun, levergun, etc.)
But I've found myself taking a liking to old guns more than anything. More than that, I've found myself buying mil-surps more than anything else. I don't think it was ever an intentional decision, but mil-surps tend to be cheaper and more functional than anything else out there. But here's where the subconcious takes over I think; even if they're not cheaper, I can justify paying more because I know they will do everything I ask them to. I like all steel construction, wood, classic styled guns.
Straight mil-surp:
'42 IZZY Mosin Nagant
'43 IBM M1 Carbine
CZ82
Close to mil-surp:
'47 S&W m&p .38 spl
Just plain old:
'53 1894 Winchester .30-30
Early '70s ASM 1851 clone
I had a '34 Colt PPS that was a columbian police gun that almost fits the mil-surp category, traded it away for the S&W M&P and a beretta jetfire. Which, predictably, is also quite a bit older than I am and predictably classically styled. The newest gun I own is a Mossberg 500 that I got for my 18th birthday, plastic, tacticool. I love it, but it don't fondle it with the same affection as my older guns. Which is strange, I thought all of us 20 year old college kids were supposed to be into glocks and submachine guns we see on those flimmidy flammidy call of duty video game box machines, eh?
