From the tiniest pea-shooter to the most exotic antique flintlock, Collectors Firearms has your back. Or your hip and ankle, for that matter. Started in 1975, this Houston mainstay has been providing people with a huge inventory of quality pistols, rifles, shotguns — and even knives and swords — at great prices, with excellent customer service from real experts. Colt, Winchester, Smith & Wesson, SIG Sauer — whatever your brand, you won't be disappointed. Collectors Firearms boasts a regular inventory of more than 12,000 guns, from as low as $100 to $500,000. (We like to stick somewhere in the middle.) You can also salivate over the new arrivals, along with the regular stock, online.
