CAPE CORAL, Fla., -- A man accidentally discharged his semiautomatic hand gun Friday while shopping for ammunition inside the retail portion of Shoot Center, a gun store in Cape Coral.

"We always assume you have a loaded firearm," said Shoot Center Owner, Aaron Forum, describing store protocol for anyone that pulls out a gun.

Forum took to Facebook to explain the incident:

"On Friday April 6th, at approximately 11AM, a customer ignored posted signs at the entrance to Shoot Center, ignored the commands of Shoot Center staff, removed a loaded firearm from his pocket and negligently discharged his firearm into the floor of our facility. This customer was not trained by Shoot Center staff nor was he a frequent customer of Shoot Center."

His discharge left a bullet hole in the ground of the floor. Forum tells Fox 4 the customer was banned from the store and will be detained by deputies if he returns.

“This is a constant concern of ours, which is why we have a blanket zero tolerance policy.”

Shoot Center policy states that "no uncased firearms" are allowed unless the customer has a Concealed Weapons License.

The store offers free conceal cases for customers with loaded firearms.

Forum says the incident gives opportunity to talk about gun safety. He created a video on safety on Facebook. You can see the video here.

No was injured during the incident.
