Sig Sauer P320 Pistols

The Sig Sauer P320 is one of the most versatile handgun platforms in the SIG Sauer lineup. Built around a modular fire control unit, the P320 family gives shooters a wide range of options, from compact carry pistols to full-size duty models, competition-focused builds, compensated variants, and large-frame 10mm configurations.

This collection includes popular P320 models such as the P320 Compact, P320 Full-Size, P320 XCompact, P320 XCarry, P320 XFull, P320 AXG, P320 AXG Legion, P320 XFIVE Legion, P320 Spectre Comp, P320 MAX, P320 XTEN, and other factory configurations. You will also find optic-ready models, manual-safety variants, state-compliant versions, and factory optic packages when available.

Why Choose a Sig Sauer P320?

The P320 is known for its modularity. Depending on the model, shooters can choose different grip sizes, slide lengths, optic cuts, barrel lengths, trigger styles, frame materials, and magazine capacities. That makes the P320 platform useful for concealed carry, home defense, duty use, competition, range training, and hunting-focused 10mm applications.

Common P320 features may include:

• Modular P320 fire control unit system
• Compact, carry, full-size, and XSeries configurations
• Optic-ready slide options
• Flat trigger and XSeries trigger options
• Polymer, AXG alloy, TXG tungsten-infused, and steel-frame variants
• Integrated compensator options on select models
• 9mm, .45 ACP, and 10mm model options depending on variant
• Manual-safety and non-manual-safety configurations
• State-compliant 10-round versions where available

Popular Sig Sauer P320 Models

The standard P320 Compact and Full-Size models are straightforward options for buyers who want a reliable striker-fired SIG pistol without the added cost of competition or custom-shop upgrades.

The P320 XCompact, XCarry, and XFull models add XSeries features such as upgraded grip modules, flat triggers, improved ergonomics, and optic-ready configurations on many variants.

The P320 AXG and AXG Legion models use alloy grip modules for shooters who prefer a more traditional metal-frame feel with the modular benefits of the P320 platform.

The P320 XFIVE Legion is built for performance shooting, using a heavier grip module, longer slide, 5-inch barrel, and competition-focused controls.

The P320 Spectre Comp and other compensated models are designed to help reduce muzzle rise and improve control during faster shooting.

The P320 XTEN brings the P320 platform into 10mm Auto for buyers who want more power for hunting, woods carry, or range use.

Choosing the Right P320

The right P320 depends on your use case. Compact and XCompact models make sense for carry. Full-size, XFull, and M17-style models work well for duty or home defense. AXG, Legion, MAX, and Spectre Comp variants are better suited for shooters who want premium materials, reduced recoil, faster handling, or competition-ready features.

All firearm purchases must ship to a licensed FFL dealer. Always confirm magazine capacity, optic compatibility, and state restrictions before ordering.
