If I were Osage County Guns, I would do at least 2 things.
1) Make the bollards closer together, so there is NO WAY any car will fit between them.
2) Stop placing guns in glass display cases! Top Gun in Arnold, MO, (same metro area), places all of their guns on a wall, and there are metal roll-up doors that are lowered and locked over them when they are closed. Anything that can't fit behind the metal roll-up doors on the walls goes into the vault at closing time.
