A man who was part of an armed “patriot” group guarding a gun store in Oktaha, Oklahoma that recently declared itself “Muslim free” accidentally shot himself at the store on Tuesday, according to local reports.

The unidentified man was part of a self-described “patriot” group guarding the Save Yourself Survival and Tactical Gear store. Its owners said they began receiving death threats after they posted a sign on their door that said it was a “Muslim free” establishment, according to KOTV.

The gun fell out of the holster and discharged, with a bullet hitting the man in the wrist, Muskogee County Sheriff Charles Pearson said, according to KOTV and the Tulsa World newspaper. The man was expected to survive.

“I saw several of those gentlemen out there yesterday,” Pearson told muskogeenow.com. “The way they were holding their weapons, with the fingers on the triggers, you can tell a couple of these gentlemen have no idea about weapons safety. It’s like the Clampetts have come to town.”

A “Muslim-free” gun shop in Florida made headlines this week after George Zimmerman, the man who shot unarmed black teenager Trayvon Martin, said he would raffle off a painting of the Confederate flag to fundraise for the shop.
