CONCORD, N.H. (AP) — Police and federal law enforcement officers are among 20 people from multiple states including Wisconsin saying they were wounded by a popular type of Sig Sauer pistol. It’s the latest lawsuit alleging that the gun is susceptible to going off without the trigger being pulled. The lawsuit was filed Wednesday in New Hampshire federal court. It says there have been more than 100 incidents of the P320 pistol unintentionally discharging when the user believed they did not pull the trigger. In many cases described, the gun discharged while still in the user’s holster, seriously injuring them. Sig Sauer says the gun is designed to fire when the trigger is pulled, and includes internal safeties that prevent the firearm from discharging.
