SIG P320 Complete Guide 2026: All 7 Models, M17 vs M18 & Safety Update

The SIG Sauer P320 in 2026 is two stories in one — a genuinely brilliant modular pistol that still serves the U.S. Army, and the subject of over 100 active lawsuits alleging it can fire without anyone touching the trigger. This guide covers the entire P320 family (Full Size, Compact, Carry, X-Five Legion, M17, M18, AXG, XTEN), the head-to-head M17 vs M18 differences that confuse most first-time buyers, the 2025–2026 recall/lawsuit landscape including the IDPA ban and ICE departure, and finally — for shooters who want to train without burning live ammo — the SIG-licensed VFC ProForce M17/M18 airsoft replicas and how to use them for draw, reload, and Bill Drill practice with the AirsoftShotTimer app.
