Featuring adjustable retention, a full sweat guard, and veteran craftsmanship in the USA, it ensures a secure, consistent draw and all-day comfort for professionals and enthusiasts who demand reliability and tactical readiness. ## Description The Watchdog Tactical Kydex holster for the FN 510/545 Tactical with Surefire X300 is built for people who run a weapon light and need the whole setup to sit in the same place every time. The shell is molded over the pistol with the light attached, so the two are carried as a single unit rather than a pistol squeezed into a holster that was never cut for a light. This holster is made specifically for the Surefire X300. The bezel clears the shell, the light stays mounted between carry and the range, and there is no need to strip the light off to holster the gun. It is also cut for a mounted red dot, so an RMR-pattern optic clears without modification. Retention adjusts through a single tension screw, letting you run a lighter break for range work and firmer retention for carry. This is the outside the waistband version. It rides on the belt for faster access and all-day comfort, which suits range work, duty use, and open carry where concealment is not the priority. The Kydex shell holds its shape when the pistol is drawn, so you can re-holster one-handed without the mouth collapsing. Competitive shooters, law enforcement officers, firearms instructors, and anyone who runs a light on their carry gun all want the same thing: the light stays on, the draw stays consistent, and the holster does not become the weak point. This one is built around that. Watchdog Tactical is a North Carolina manufacturer, and every holster is made in the United States by American veterans. We build to order rather than pulling generic shells off a shelf, we inspect each holster before it ships, and if something is not right you talk to the people who made it. ## Features - PRECISION MOLDED FIT — Formed over the FN 510 545 Tactical with the Surefire X300 already mounted, so pistol and light seat as one unit. No flex, no rattle, and the same index on every draw. - BUILT FOR THE SUREFIRE X300 — This shell is cut for the Surefire X300 and fits both the X300A and the X300B. The light stays mounted, the bezel clears the shell, and you keep one setup for carry and range work. - ADJUSTABLE RETENTION — A single tension screw sets the draw exactly where you want it, from a light range break to firm retention for everyday carry. Set it once and it holds through thousands of repetitions. - FULL SWEAT GUARD, STANDARD — Every holster ships with a sweat guard that keeps the slide off your skin and moisture off your firearm. Not an upcharge, not an option — it is built into every holster we make. - MADE IN NORTH CAROLINA BY VETERANS — Built in our North Carolina shop by American veterans, inspected before it ships, and backed by a support team you can actually reach. Outside the waistband carry. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0FVGNVH19 | | Best Sellers Rank | #1,056,071 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #12,297 in Gun Holsters | | Brand Name | Watchdog Tactical | | Closure Type | Screws | | Color | Black or Tan | | Customer Reviews | 3.5 3.5 out of 5 stars (2) | | Hand Orientation | Tan Right Handed | | Included Components | Holster | | Manufacturer | Watchdog Tactical | | Material Type | Thermoplastic Polyurethane | | Mounting Type | Outside The Waistband | | Number of Items | 1 | | Product Style | Outside the Waistband w/ X300 | | UPC | 810192853588 | | Unit Count | 1 Count | | Warranty Description | Limited Lifetime | ## Product Details - **Brand:** Watchdog Tactical - **Closure Type:** Screws - **Color:** Black or Tan - **Hand Orientation:** Tan Right Handed - **Manufacturer:** Watchdog Tactical - **Material:** Thermoplastic Polyurethane - **Number of Items:** 1 - **Style:** Outside the Waistband w/ X300 - **UPC:** 810192853588 - **Unit Count:** 1 Count ## Images ![OWB Kydex Holster for FN 510 545 Tactical with Surefire X300 | Right Hand | Light Bearing | Optic Ready RMR Cut | Adjustable Retention | Sweat Guard | Made in USA - Image 1](https://m.media-amazon.com/images/I/61sfOzI+wHL.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/807205950-owb-kydex-holster-for-fn-510-545-tactical-with-surefire](https://www.desertcart.tn/products/807205950-owb-kydex-holster-for-fn-510-545-tactical-with-surefire) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-23*
