My M&P .40 does not have a manuel safety but I prefer it did. I didn't catch it when I bought it....I basically assumed all of them did due to the pic I saw of one before I bought it. Below is a current article I copied and pasted from WRAL TV in Raleigh, N.C. and I imagine the local law enforcement here use Glocks.

Fayetteville, N.C. — A Cumberland County Sheriff's Office deputy was wounded Wednesday morning when his service weapon accidentally fired as he was leaving home to drive to work, authorities said.

Maj. John R. McRainey, the chief jailer at the Cumberland County Detention Center, underwent surgery at Cape Fear Valley Medical Center and was in stable condition.

McRainey was putting a bag in his vehicle when his .40-caliber semiautomatic handgun, which was inside the bag, discharged, authorities said. Investigators said the gun apparently bumped against another item in the bag, which McRainey often used to transport the gun.

"Although it is always a tragedy anytime that anyone suffers a gunshot wound, we are just thankful that it was no worse than it was," Sheriff Earl "Moose" Butler said in a statement.
