SIG SAUER P320 9MM LUGER (9x19 PARA)
Description:
Guns Listing ID: 580523
SIG Sauer P320 — Complete Description
The SIG Sauer P320 is a modular, striker-fired, semi-automatic pistol introduced by SIG Sauer in 2014. Its defining characteristic is a serialized, removable fire-control unit (FCU) that allows the shooter to reconfigure the pistol across multiple grip sizes, slide lengths, calibers, and frame types without requiring a gunsmith — a design that helped the P320 earn broad commercial and law-enforcement adoption (including military variants). The P320 family spans compact carry pistols up to competition and duty models, and includes optics-ready slides, enhanced triggers, and multiple safety/configuration options.
Key Features (general / family-wide)
Action: Striker-fired, semi-automatic
Modular design: Serialized fire-control unit (FCU) removable from the grip module; swap frames, slides, barrels and change calibers with the same serialized core
Calibers (common): 9×19mm Parabellum (most common), .40 S&W, .357 SIG, .45 ACP (via caliber-specific kits)
Configurations: Full-size (Duty/Full), Carry/Compact, XCompact / XFull / XSeries (enhanced), M17/M18 (military), Legion (competition/weighted), P320-XCompact, P320-Carry, P320-AXG, etc.
Sights: Factory three-dot steel sights; many models are optics-ready with removable plate cut for popular red-dot footprints (e.g., Shield RMSc, SRO, etc.). Night sight options available (tritium)
Accessory rail: MIL-STD-1913 (Picatinny) rail on most full and compact dust covers for lights/lasers
Trigger: Factory triggers vary by model — standard factory trigger (short reset), XSeries features enhanced triggers (shorter pull, crisper break), some models offer flat or performance triggers
Safety options: Models exist with and without a manual thumb safety; internal safeties include striker block and disconnector systems (dependent on model/year)
Finish & materials: Steel slide and barrel with nitride, stainless, or other finishes; polymer grip modules in several textures and colors; XSeries and Legion use upgraded materials/finishes in some variants
Typical Technical Specifications (examples / ranges)
NOTE: exact numbers depend on the variant (Carry, Compact, Full, X-Series, Legion, M17/M18). I list common values and note where variants differ.
Barrel length: typically 3.6\"–4.7\" (compact/Carry around 3.6–3.9\", full-size/service around 4.7–5.0\"; XSeries and competition models vary)
Overall length: roughly 7.2\"–8.0\" depending on barrel/slide length
Height: ~4.7\"–5.5\" depending on grip and magazine used
Width: approximately 1.1\"–1.4\" (slide width varies by model)
Weight (unloaded): ~22–40 oz (polymer carry models lighter; Legion and some XSeries heavier due to metal components or tungsten-infused grips)
Magazine capacity (9mm): common factory magazines from 10 to 17 rounds, depending on jurisdiction and model; compact/Carry versions typically ship with 10–15-round magazines, full-size commonly 15–17 rounds. Other calibers use capacity-appropriate magazines (e.g., .45 ACP lower round counts).
Frame material: Polymer grip modules standard; some XSeries/Legion offer alloy or tungsten-infused modules for increased mass and reduced recoil
Slide material: Stainless or alloy steel; treated finishes include nitride, black oxide, or stainless
