Sig Sauer Holsters

Alien Gear Holsters offers a full range of custom-fit holsters for Sig Sauer handguns, including popular models like the P365, P320, P226, and P938. Each holster is engineered to match the unique contours of Sig's striker-fired and hammer-fired pistols. Whether you're carrying the compact P365 for concealed carry or the full-size P226 for duty use, Alien Gear ensures retention, comfort, and adaptability for all carry styles — including IWB (inside the waistband), OWB (outside the waistband), appendix carry, shoulder rigs, ankle holsters, and more.

These holsters are preferred by law enforcement, military, CCW permit holders, and civilian carriers for their adjustable retention, modular attachments, and American-made reliability.

 

Why SIG Sauer Owners Rely on Alien Gear Holsters

From modular platforms to compact carry pistols, SIG Sauer firearms bring innovation — but also introduce holster-specific challenges. At Alien Gear Holsters, we engineer solutions to match the advanced features of your SIG. Whether you're carrying a P365, P320, Legion, or X-series model, our holsters are built to perform with modern SIG platforms in real carry conditions.

Modular Compatibility for P320 Grip & Slide Swaps

Our holsters are tested to match SIG’s modular FCU platform. Whether you're running a Compact grip with a Full slide or a Carry frame with a threaded barrel, we provide secure fitment without guessing.

Benefit: Confident carry across all your modular P320 configurations.

Perfect Match for Every P365 Variant

We offer holsters shaped specifically for the P365, P365X, and P365XL — with the right ride height, slide length coverage, and trigger guard lock-up.

Benefit: Zero overhang. Zero slide drag. Just a perfect fit every time.

Optic-Ready by Design

Alien Gear holsters come pre-cut for ROMEOZero, Shield RMSc, and other red dots — giving your slide-mounted optic the clearance it needs without sacrificing retention or draw smoothness.

Benefit: Carry your RDS-equipped SIG with confidence and speed.

Concealment Support for Aggressive Grip Modules

Our holsters minimize grip printing and skin irritation by using foam wedges, adjustable cant, and sweat guards that work with Wilson Combat, XCarry, and TXG grip modules.

Benefit: Keep your concealed SIG hidden — and comfortable — all day.

True Trigger Guard Protection for Striker-Fired P320s

With no external safety, the P320 demands a holster that covers the trigger completely. We mold retention into the guard and frame — never leaving gaps.

Benefit: Safe, confident carry — even with a round in the chamber.

Retention Tuning for the P365 Frame

We use precision molding and adjustable retention to hold the slim P365 securely — without over-tightening or slide wear.

Benefit: Custom-grade retention for one of the most popular micro-compacts.

Comp & Threaded Barrel Support

Running a comp or suppressor-ready barrel on your SIG? Our open-muzzle designs and optional barrel sleeves handle the added length while protecting your gear.

Benefit: Modern setups. Modern support. Carry your upgrades with no compromise.

Engineered for the X-Series

We shape our shells around the XCompact, XFull, and XCarry series — including magwell flares and slide cuts — for a clean draw and consistent lock-in.

Benefit: Finally, a holster built specifically for your X-Series pistol.

Support for Legion Weight and Balance

Our holsters are built with reinforced clips and backers that keep heavy steel-frame SIGs like the P226 Legion from tipping or sagging.

Benefit: Solid retention and balance — even with full-metal pistols.

Suppressor-Height Sight Channels

We provide elevated sight tracks that accommodate tall factory sights without hang-ups or extra friction during the draw.

Benefit: No more scraping or sight binding — just smooth draw every time.

Manual Safety Clearance for M18/M17 Users

Alien Gear holsters include optional cuts and spacing for manual safety levers on SIG variants like the M17, M18, and P320 Carry with thumb safety.

Benefit: Your holster supports your configuration — not the other way around.

Perfect Fit for Light-Bearing SIGs

Choose from models configured for TLR-7 Sub, X300U, or OLIGHT PL-Mini — all molded specifically for SIG rail geometry and profile.

Benefit: Secure carry for your duty-ready, WML-equipped SIG — without light wobble or frame gaps.

Appendix Carry for Wide SIG Slides

We build appendix rigs with built-in claw, wedge, ride height, and sweat shield adjustments to manage the wider footprint of the P320, P226, and P229.

Benefit: Concealed comfort, even with a full-size SIG — seated, standing, or moving.

Chest Holster Options for Backcountry SIG Carriers

Our ShapeShift chest rig supports SIGs with optics, lights, and suppressor sights — making it ideal for trail defense, outdoor carry, or search-and-rescue.

Benefit: Take your SIG into the wild — secure, stable, and ready for anything.

Always Up to Date With New SIG Models

We move fast to support new SIG releases — including P365AXG, XTen, and new FCU-compatible configurations — with high-quality shells and quick ship times.

Benefit: Get the holster you need, when your new SIG hits your hand — not months later.
