Sig Sauer P320 & Align Tactical Thumb Rest & TLR-1 HL-X Duty & Competition Holster

Sig Sauer P320 Outside Waistband Light Duty & Competition Kydex Holster

This outside waistband (OWB) light duty and competition holster is custom-designed for the Sig Sauer P320 series pistols, paired with the Streamlight TLR-1 HL-X and TLR-1 HL-X USB weapon-mounted lights, and compatible with the Align Tactical® Thumb Rest Takedown Lever.

Firearm Compatibility

This Kydex holster has been precision-tested to fit the following P320 models:

• Sig Sauer P320 Full Size
• Sig Sauer P320 Carry
• Sig Sauer P320 M17
• Sig Sauer P320 M18
• Sig Sauer P320 AXG Pro
• Sig Sauer P320 X5 Legion

Please note: Holsters that support Align Tactical®, Gas Pedal®, and Tactical Development aftermarket accessories are non-returnable except for workmanship issues, as these parts affect both concealability and comfort.

Light Compatibility

Retention is engineered on the Streamlight TLR-1 HL-X or TLR-1 HL-X USB light, not the pistol itself. This means the holster will not function without the light attached. The 1913 keys are standard for this setup.

⚠️ This holster does not fit the Streamlight TLR-1 or TLR-1 HL models.

Learn more about the Streamlight TLR-1 HL-X weapon light. Our preferred option is the Streamlight TLR-1 HL-X USB, available directly from Four Brothers.
