I got my mosin nagant for $80 when I was 16 years old.
The Glock 17 is my all time favorite gun. I don't need a picture of that.
Close runner ups are
The Stoeger Coach Gun 12 gauge. This would be a shotgun I would take camping to take care of anything less than bear. If I had to deal with bears, it would be a "tracking gun" with a lever action in no less than .44 magnum.
The Stoeger Coach gun weighs in at 6 lbs and you can break it in two, so it'll fit in a backpack without too much trouble.
The G2 Contender single shot break action pistol with any flavor of caliber that you choose. The barrel can be switched out in a few seconds to any kind of caliber. This is THE pistol for long range, accurate pistol shooters. Many folks say that it's the most accurate gun you'll ever fire for certain calibers. I want one with .22, .223, .308 and 12 gauge barrels.
The Taurus 608 .357 Magnum with a 4 inch ported barrel (stainless steel) would be an awesome bedpost revolver. It holds
eight shots and if you run out of ammo, you can always beat your assailant to death. It weighs 3.5 pounds.
This is the Ruger Sp101. It holds five shots in .357, but it is a very, very solid gun and it can shoot .357 all day long. Most guns in this size can not and will not do that. This would be my ideal conceal and carry for certain situations.
The DP-12 is a double barreled pump action bullpup shotgun. This would be my home defense shotgun if I ever got the money for it. It holds 16 rounds of 12 gauge, which should be enough to fuck up anything that comes to your door. See, I don't much care for .223 for home defense.
OK that's enough gun porn for me today.
