Gun Stores in Missouri, KC area.
I've checked a few gun stores in the KC area:
Showmeshooters- Claycomo, MO.
Armsmart USA- Independence, MO.
US Gun Specialties- Gladstone, MO.
Great Guns- Kearney, MO.
The Armory- Kearney, MO.
G.U.N.S. Unlimited- Gladstone, MO.
A&J Gunsmithing- Raytown, MO.
There were a few others shops, but I can't remember them all.
The only stores with any inventory (rifles, pistols, shotguns) were Showmeshooters and US Gun Specialties. Armsmart USA had quite a selection, but when a store has a Romanian AK is $700 and a Mosin-Nagant is $150 (basic MN), they aren't worth talking about. Great Guns has an inventory of Shotguns and Bolt Rifles, and a few semi-autos. But the guy behind the counter is almost always an ass, his help should be running the store, not him. Pistols were only basic, and pricey.
The Armory in Kearney looked almost barren when it came to guns, but they had a ton of firearm accessories and clothes (tacticool clothes). Another barren shop (and I mean almost completely Barren) was G.U.N.S. Unlimited. He should change the shops name to "G.U.N.S. Limited", as his walls were nearly bare of all things firearms. A&J Gunsmithing also had a limited stock. But then again, they're primarily a Gunsmith, not a retailer.
There were so many other stores I walked into and the walls were bare, the cases empty, and only a few targets on the rack that I couldn't possibly list them all, it would take hours and a few more trips out to make sure I'm not mixing anything up.
I've written this up as a Missouri-side rating of these stores because quite frankly, inventory in western MO is almost non-existent. It took me three tries to find a Mini-14, and even then it was pricey. GOOD, affordable handguns are also becoming rare. You can always ditch quality and say "I'll try and fix it up", but even the fixer-uppers are starting to become scarce. Hopefully this panic ends soon, it's driving potential first-time buyers like myself absolutely mad trying to find affordable and decent quality firearms.
