Ever wonder why some fun stores won’t let you carry loaded guns on the premises? And some even prohibit outside gats altogether? You’ll read some cranky Armed Intelligentsia comments on the subject here from time to time. But incidents and accidents like this, from kdvr.com, may have something to do with those policies: “An employee of a gun supply store was shot in the arm after a gun was accidentally fired Saturday afternoon.” Not a lot of details, but we’d lay at least even money the gun that “went off” at Rocky Mountain Shooters Supply was brought in from the outside. We all know the corner gun store can be cavalcade of rule two violations, with more lasering going on that at the Crimson Trace test facility. Most people shrug it off, though, figuring the guns aren’t loaded. And they’re usually not. Until they are. Heads up.
