Telling you, Hardware stores- Lowes, Home Depot, etc... Or Sporting goods stores- Sportsmans Warehouse, Bass Pro, etc.

I did a deal at Target one night, and there was a patrol car in the parking lot obviously looking for someone, and he never paid attention to us at all, which probably has more to do with the fact I examined the pistol he traded me with it held inside his Jeep, and he examined the AR I traded him ducked out behind my trunk. Discretion is the better part of valor.
