Mission First Tactical Pro Series IWB Light Holster for Sig P320 X Carry/M18 with TLR7 Black Ambi

The Mission First Tactical Pro Series IWB Light Holster for Sig P320 X Carry/M18 with TLR7 is purpose-built for shooters who carry daily with a weaponlight mounted to their pistol. This inside-the-waistband holster combines a minimalist profile with the retention and stability needed for active carry, whether you're at the range, in the field, or managing personal protection duties. MFT engineered this holster around the reality of modern carry: you want a light on your gun, and your holster needs to work reliably with it.

The Pro Series uses an in-line magnetic retention system (ILMRS) with an 11-pound neodymium magnet that holds your fully loaded Sig securely without mechanical locks or thumb breaks—retention is independent of the weapon-mounted light, so your gun stays put regardless of how the TLR7 is positioned. The integrated barrel stabilizer insert (IBSI) keeps the pistol aligned with the holster body, maintaining consistent geometry whether you're running the light or going bare. This matters for both draw consistency and for keeping the gun stable during movement.

Concealment and comfort are where this holster shines for everyday carry. A built-in vertical wedge brings the grip closer to your body, and the mid-height sweat guard limits contact between the pistol and your skin during long days in a belt. The ambi design accommodates both right- and left-hand carry, with 15 degrees of adjustable cant and multiple ride height settings so you can dial in your preferred position. Two tuckable 1.5-inch belt clips and one standard clip come in the box, and the holster converts between IWB and OWB carry. Full trigger guard coverage and a softened radius design eliminate hotspots that develop during extended wear.

Built in the USA at MFT facilities, each holster is handmade to precise tolerances for the P320 X Carry/M18 platform. The holster accommodates the Streamlight TLR7, TLR7A, TLR7X, and TLR7 HL-X, plus several Surefire and Nightstick options, making it adaptable as your gear evolves.

Frequently Asked Questions

Will this holster work with other Streamlight or Surefire lights?

Yes. The Pro Series is approved for Streamlight TLR7, TLR7A, TLR7X, and TLR7 HL-X models, as well as Surefire XC1, XC2, and XC3. It also accommodates Nightstick TCM-550XL and Inforce Wild 1 lights. If you're using a different light, check with MFT to confirm compatibility.

Can I carry this holster appendix and on my hip?

Yes. The Pro Series is convertible between inside-the-waistband (IWB) and outside-the-waistband (OWB) carry, and the ambidextrous design works for both right- and left-hand positions. Adjustable ride height and cant allow you to fine-tune placement for your preferred carry location.

What's included in the box?

The holster comes with two tuckable 1.5-inch belt clips and one standard 1.5-inch belt clip, giving you options for how you want to mount it to your belt.

Does retention depend on the weapon light being mounted?

No. The in-line magnetic retention system (ILMRS) works independently of the weapon-mounted light, so your gun stays secure whether or not the light is attached. This is important for reliability and flexibility as your setup evolves.

Is this holster suitable for threaded barrels or compensators?

No. This holster is not recommended for use with threaded barrels, compensators, or other firearm modifications, as these may cause function issues. Stick with your P320 X Carry/M18 in stock configuration for best results.
