Sadly, my love of firearms is mostly in theory as I'm too poor to buy all the stuff I want. At the moment, I'm limited to one old double-barrel 12ga shotgun I inherited.
Now, in a few years when the money improves, I have a list. SPAS-12 semi-auto shotgun, Sig P220 .45, Sig P226 9mm (with the .22 conversion as well), Sig 556, AR-15 and AK-47 (semi-auto versions, of course). It'll take some time and saving up, but what a fun little arsenal to have :)
