SIG SAUER P320

Overview

The SIG Sauer P320 is a modular, striker-fired semi-automatic pistol introduced in 2014. Its defining feature is a removable stainless-steel Fire Control Unit (FCU), which is the serialized component. This allows users to swap grip modules, slide assemblies, and certain calibers (where compatible) without replacing the serialized firearm.Some key points:Action: Striker-firedCommon calibers: 9mm, .40 S&W, .357 SIG, .45 ACP, and some 10mm modelsSizes: Full-Size, Carry, Compact, XCompact, XFive, and othersMilitary variants: The U.S. military adopted versions of the P320 as the M17 and M18 service pistols.The P320 is well regarded for:Excellent modularity and customizationGood ergonomicsWide aftermarket supportStrong accuracy and reliability in many independent reviewsThere has also been significant public attention regarding reports and lawsuits alleging unintended discharges in some circumstances. SIG Sauer has consistently stated that the P320 is safe when used as intended, points to its internal safety systems, and has offered a voluntary upgrade program for earlier production models. The issue remains the subject of ongoing litigation and debate.If you're interested in a specific aspect, I can help with:Differences between the P320 and other striker-fired pistolsM17 vs. M18 comparisonChoosing the right P320 modelHistory of the safety concerns and the voluntary upgrade programField stripping, maintenance, or general operation (safe handling only)
