The Ultimate Sig Sauer P320 Holster: Precision-Fit Security, All-Day Comfort — Proudly Made in the USA

The Sig Sauer P320 is renowned for its modular design, battlefield-proven reliability, and outstanding versatility. But all that potential is only as strong as the holster that supports it.

Our American-made P320 holsters are engineered to match the exact slide and grip profile of every P320 variant, delivering unmatched safety, ergonomic comfort, and professional-grade performance.

Engineered for Every Sig Sauer P320 Variant

Whether you rely on the P320 Full Size for duty use, the P320 Compact or Carry for concealed carry, or the advanced P320 XFive Legion for competition, our holsters are molded for your specific configuration. We cover the full spectrum — Compact, Subcompact, Carry, M17, M18, XCarry, XFull, XCompact, and even the highly specialized XFive Legion.

This precise molding ensures perfect retention, consistent draw stroke, and full trigger guard coverage — eliminating guesswork and preventing dangerous misfits.

Sig Sauer P320 Holsters Ready for Lights, Optics, and Custom Attachments

Modern users often run weapon-mounted lights or red dot optics on their P320s. Our holsters are designed to fully support light-bearing setups, including configurations with the Streamlight TLR-7A, Nightstick TCM-550XL, and similar accessories. 

Each light-compatible holster maintains robust retention and protects your trigger, giving you the confidence to run advanced setups without compromise.

Concealed Carry, Refined

For everyday concealed carriers, our inside-the-waistband (IWB) and appendix (AIWB) holsters deliver discreet comfort without sacrificing readiness. The Cloak, ShapeShift, and Low-Pro lines provide a slim profile, customizable ride height, adjustable cant, and retention settings tailored to your needs. 

Our AIWB designs also minimize printing and provide superior comfort while sitting or moving — crucial for all-day, every-day carry.

Duty-Grade Strength for Professionals

Law enforcement officers, military personnel, and open carriers demand rugged durability and secure retention. Our RAPID FORCE® series offers Level II retention with intuitive thumb-release mechanisms, robust external mounting options, and rock-solid construction to keep your firearm secure under extreme stress.

Trusted by professionals nationwide, these holsters ensure your Sig P320 remains locked in until you decide otherwise — and releases instantly when seconds matter.

Versatility for the Backcountry and Beyond

For outdoor adventurers, hunters, or overland enthusiasts, chest holsters and drop leg platforms provide critical accessibility when waistband carry isn't practical. Our chest holsters keep your Sig P320 XFull, XFive Legion, or XTEN accessible during backcountry treks, long hikes, or while operating heavy gear, all while maintaining supreme stability and comfort.

Flawless Integration with the P320’s Modular System

The P320’s modularity allows grip module swaps and custom configurations — but holster fitment must be precise. Our holsters are sculpted to match the exact slide length and frame dimensions, guaranteeing reliable retention and safe draw regardless of your internal fire control unit or customized grip module. You can swap grips and slides, knowing your holster will remain mission-ready.
