A Tampa police officer has sued Sig Sauer, alleging that his P320 fired by itself while holstered wounding him in the leg, according to a local ABC television affiliate.

The officer claims he was working an off-duty job in February of last year when he “brushed his service belt to try to attach a set of keys, he said his department-issued firearm fired by itself while holstered.”

“As soon as I touched my gun, it went off. When it happened I didn’t know if someone was shooting at me or what had happened. But it just scared the devil out of me,” Northrop told the TV station.

The round shattered bones in his leg and ankle, and required metal rods and multiple surgeries.

According to the complaint, the officer is suing Sig Sauer, “for the design, manufacture, sale, distribution and inadequate warnings relating to an unreasonably dangerous and defective firearm.”

After drop-safety issues were raised about the 320, Tampa Police Department participated in a manufacturer’s upgrade program and received new guns.

The officer qualified with his new “upgraded” handgun in April 2019.

Tampa PD was not named in the lawsuit, and Sig Sauer did not comment about the pending litigation.
