Whether you're looking for a fancy new SIG Sauer or a pair of antique flintlock duelers, Collectors Firearms is your target. What began in 1975 as a 600-square-foot shop has grown into a major showcase boasting an inventory of more than 7,000 guns as well as a ton of ammo, scopes and other accessories. The weaponry lining the walls and display cases is vast, and features everything from new and pre-owned pistols, rifles and shotguns to samurai swords and military antiques. One thing we really like is the continually updated inventory on the website, so you can keep up with new acquisitions, like a brand-new Glock 17 9 mm and an ultra-rare Mannlicher carbine. This place is No. 1 with a bullet.
