i guess too many stories about both cops and other people shooting themselves when holstering.
Today, Richmond VA (Glock too) :
Guard wounded by his own pistol
Richmond Times-Dispatch Feb 28, 2007
A security guard at the federal courthouse in downtown Richmond was slightly wounded this morning when a handgun he was handling accidentally discharged.
The guard was grazed in the right upper thigh area by a lone bullet fired from a .40-caliber Glock 23 pistol, and he was taken to VCU Medical Center, where he was treated and released, said Jim Daley, the supervising deputy in charge of the U.S. Marshals Service in Richmond.
The guard, whose name was not released, is employed by Akal Security, which provides 22 security officers for the courthouse at 10th and East Main streets.
Daley said the guard had just reported for work about 7 a.m. and was putting on his equipment in a third-floor room used to store weapons, radios and other equipment. As the guard was putting the gun in his holster, it discharged, Daley said.
The bullet struck a filing cabinet and broke apart. No other injuries were reported.
Authorities are unsure why the weapon fired, Daley said. The Glock 23 has no external safety.
"We're going to check and make sure there are no defects with the gun and go from there," he said.
