The SIG Sauer P320 is a modular striker-fired semi-automatic pistol made by SIG Sauer, Inc., SIG Sauer's American branch. It marked Sig Sauer's first foray into striker-fired pistols, as their first offering on the commercial market.

The P320 has faced scrutiny over reports of unintentional discharges and safety issues, leading to over 100 lawsuits against SIG Sauer, and its withdrawal from use by several law enforcement agencies, as well as being banned from use in IDPA-sanctioned competitions and numerous ranges and training courses.
