Type: Modular semi-automatic pistol. Origin: United States / Germany / Switzerland lineage. Introduced: 2014. Action: short-recoil, striker-fired. Common caliber(s): 9mm most common; also .40 S&W, .357 SIG, .45 ACP variants. Description: The SIG Sauer P320 is a modular striker-fired pistol built around a removable fire-control unit. This allows grip modules, slides, and calibers to be changed more easily than on traditional pistol designs. A variant was adopted by the U.S. military as the M17/M18. Its strengths include modularity, ergonomics, accuracy potential, and broad institutional support. Common discussion points include trigger feel, model differences, and the importance of current-production safety updates and proper holster compatibility. Strengths generally include the role-specific advantages described above, while limitations include age, weight, recoil, cost, ammunition logistics, or reduced practicality depending on the model and configuration.
