Columbia:
Black RIfles on Vandiver –– first road north of I-70, just west of Rangeline (next to Jim's Bike & Key) –– just opened opened. It's CMMG's candy store. Lots of AR's, receivers in stock
Tiger Pawn –– Business Loop 70 near College Blvd –– not a lot of guns but prices are generally fair. Will cut you a deal generally
Family Pawn, Business Loop 70 –– Business Loop at Rangeline –– A good selection of FUDD guns, a few handguns, a couple of "blacker" type rifles. Prices are often a tad high but these guys will generally deal with you.
Family Pawn, Route B — Paris Road/Route B, north of Vandiver (just past the MFA grain tower) –– Lots of guns but stupid prices and often even more ridiculous clerks. Generally a complete waste of time.
Powder Horn Gun SHop –– hidden in an industrial building on Route B/Parris Road –– Lots of guns. Good guys. They don't give anything away, though.
Target Masters — north on Rangeline (Hwy 763?) –– an indoor range that sells some guns. I've never bought anything there so I can't say how they deal.
Bass Pro Shops –– along Hwy 63, north of I-70 –– new stuff obviously, some used (trade ins)
Jefferson City (30 miles south of Columbia)
Boggs Creek –– at Eastland and E. McCarty –– Mostly FUDD guns. Sticker prices are high but cash talks. Good selection of reloading stuff.
Bob's Guns –– west of town on Hwy 50 at Hwy T –– Lots of guns. Lots of handguns. Lots of knives (old and old school). A bunch of semi-collectable gun (Colt nuts will have a great time). Don't expect the owner (not Bob) to come off his price much. Currently has a couple of black rifles.
House of Bargains –– on old 50 in Apache Flats –– new guns, currently has a decent stock of black rifles (mostly DPMS)
Family Pawn –– Dunklin and Missouri Blvds –– Probably 20-30 in stock at any given time. They turn them over pretty fast because they cut deals.
Aspen Ridge –– across from the Capital Mall in a shopping center –– a new store. Attempts to appeal to upscale clients. Not a lot of inventory yet, but what they have is interesting.
Trims Pawn –– Missouri Blvd –– not many guns, but prices generally fair
Mid-Missouri Pawn –– Missouri Blvd –– Why does this guy even bother unlocking the door?
J's Pawn –– East McCarty at Layfayette –– Nothing to see here
Ammo Alley –– Hwy 63 north of Jeff CIty –– Doesn't seem particularly interested in stocking guns (or ammo for that matter)
Mexico, MO (about 20 miles north of I-70, east of Columbia)
Graf and Sons –– Hwy 15 –– This great reloading supply house recently opened a "Supercenter". Lots of reloading supplies/equipment. New and used guns, too. If you're looking for a Marling 39a, they have a great deal on a used one.
Trim's Pawn –– near the square (by the KFC) –– Not a lot to see but might as well stop while you're there. Like all the Trim family pawn stores, they deal.
