San Diego Guns holds Federal Firearms License 9-33-073-01-7L-06115 as a Type 01 dealer in Grantville, San Diego, operating from Suite C at 5995 Mission Gorge Road in the 92120 ZIP. Owner Dallas Martewsen opened the shop in 2016 with a focus on customer education and responsible firearm ownership, building a retail floor around hard-to-find rifle configurations ordered direct from manufacturers. The inventory pulls from Wilson Combat, Les Baer, Nighthawk Custom, Colt, LWRC, Daniel Defense, Benelli, and Beretta, covering AR-platform rifles, bolt-action precision guns, 1911 and 2011 pistols, shotguns, and lever-action models. The Mission Gorge Road corridor through Grantville concentrates automotive and industrial businesses, and San Diego Guns shares the same light-industrial traffic flow that fills the tasting room at San Diego Brewing Company a half-mile north after work. FFL transfer fees run $100 for handguns and long guns, with other firearms processed at $25 per unit, handling online purchases shipped from out-of-state retailers through the federal background-check system. The optics counter stocks red-dot sights, magnified scopes, night-vision devices, and mounting hardware, and the accessories wall covers uppers, lowers, triggers, stocks, and barrel assemblies for AR-platform builds. Ammunition inventory spans handgun, rifle, shotgun, and rimfire calibers in range-grade and defensive loads. Range gear including rifle bags, bipods, eye and ear protection, and steel and paper targets fills a dedicated section near the same Mission Gorge Road storefront strip where Zaks Smog Check & Auto Registration processes the Grantville corridor's vehicle inspections. A rewards program tracks repeat purchases, and the FFL license expires November 1, 2027, with current ATF compliance status publicly verifiable through the Bureau's online database.
