Sig Sauer OWB Holsters – Outside the Waistband Kydex Holsters for Sig Sauer Pistols

Find a precision-molded Sig Sauer OWB holster for your exact pistol — built for outside the waistband carry that delivers consistent retention, optic compatibility, and a fast draw across the P226, P320, and P365 platforms.

Every holster in this collection is vacuum-formed specifically to the frame, trigger guard, and slide profile of your Sig Sauer model. Because the P226 full-size, the P320 modular, and the P365 micro-compact have fundamentally different frame geometries, each platform requires its own dedicated shell — and that’s exactly what you’ll find here.

Why OWB for Your Sig Sauer

Outside the waistband carry keeps the firearm on the exterior of the belt, making it the preferred setup for:

• Range training and competition — unrestricted grip access, faster draw stroke, no waistband friction during extended sessions

• Open carry and duty — stable platform against the hip, secure under physical activity

• Tactical and law enforcement use — particularly relevant for the P226 and P320/M17/M18 platforms, which are standard issue across multiple agencies and military branches

• Concealed carry under a cover garment — a properly fitted Sig Sauer OWB Kydex holster conceals cleanly under a jacket or untucked shirt

Sig Sauer Models Available in This Collection

Each holster uses a dedicated model-specific mold — not a universal shell. Select your exact Sig from the product page before ordering:

  ⚠️ Holsters for each platform are not interchangeable — P226, P320, and P365 all use separate molds. Always select your exact Sig model before adding to cart.

Kydex Shell — Construction & Features

All Sig Sauer OWB Kydex holsters in this collection are built from 0.08-inch thermoplastic Kydex — rigid, moisture-resistant, and temperature-stable for outdoor and all-weather use:

• Fully enclosed trigger guard — no clothing or debris can contact the firing mechanism during carry or reholstering

• Audible “Posi-Click” retention confirms full seating every time

• Rigid shell mouth stays open after the draw — enables safe, one-handed reholstering without looking down

• Adjustable retention via steel screw — dial in from competition-speed loose to duty-firm

• Available in Standard Kydex and Carbon Kydex finish on select models
