Lawyers at Saltz Mongeluzzi & Bendesky filed a complaint against gun manufacturer Sig Sauer Inc. on Tuesday, which is the newest of a string of suits alleging that a design flaw in a pistol produced by the company caused the weapon to discharge without being intentionally fired.

The case is among what Saltz Mongeluzzi’s Robert Zimmerman estimates to be about a dozen in-process suits claiming that the Sig Sauer P320 caused injury by firing without its trigger being pulled. According to Zimmerman, Saltz Mongeluzzi is representing the plaintiffs in seven of those cases, spanning Pennsylvania, Florida, New York and Oklahoma.
