The FN 510 MRD is what happens when a company with a long history of building duty-grade firearms decides to do a 10mm right. Built on a foundation closely related to the well-regarded FN 509 platform, the 510 MRD scales everything up to handle the demands of the 10mm Auto cartridge without sacrificing the ergonomics or shootability that make a pistol actually enjoyable to run. The 4.1-inch cold hammer-forged, target-crowned barrel keeps the profile clean and flush with the slide, and the polished feed ramp is there to make sure it runs reliably with the wide variety of 10mm loads on the market, from standard FMJ practice ammo to the hotter hunting and defense loads.
FN's patented Low-Profile Optics Mounting System is the real centerpiece here. The slide is machined to accept all major red dot footprints, including Trijicon RMR/SRO, Holosun 507/508, Leupold DeltaPoint Pro, Vortex Venom/Viper/Razor, and more, using the four included MRD mounting plates. You can have a dot mounted and zeroed in minutes without touching a gunsmith. The driftable steel co-witness sights are set at optic height, so they stay visible over most micro red dots and give you a solid iron-sight backup without having to swap anything out.
The grip frame is contoured specifically around a 15-round grip profile, and the two interchangeable backstraps let you dial in the fit based on your hand size. Three distinct grip texture zones work together to help manage recoil, which matters when you're running full-power 10mm. Slide stop and magazine release are both fully ambidextrous, a genuinely useful feature rather than a spec sheet checkmark. The trigger is factory-tuned to break cleanly at around 6 pounds with a short reset, and the 6.1-inch sight radius contributes to accuracy potential that punches above what you'd expect from a pistol this size.
The MIL-STD-1913 Picatinny rail up front gives you a mounting point for a weapon light, which is a practical addition for a pistol this capable. A loaded chamber indicator on the slide provides a quick visual and tactile check. The 510 MRD is a strong pick for home defense, backcountry carry, or anyone who wants a thoughtfully engineered 10mm platform that's ready to run the moment it comes out of the box.
The FN 510 MRD uses FN's patented Low-Profile Optics Mounting System and comes with four MRD mounting plates that cover all major footprints. Compatible optics include the Trijicon RMR and SRO, Holosun 507 and 508 series, Leupold DeltaPoint Pro, Vortex Venom, Viper, and Razor, C-More STS2, Docter, and Burris FastFire, among others. Most optics can be mounted directly in minutes without any gunsmithing.
The main difference is the barrel. The 510 MRD has a flush-fit 4.1-inch non-threaded, target-crowned barrel, while the Tactical version has a longer 4.71-inch threaded barrel designed for suppressors and compensators. The MRD also ships with standard flush-fit magazines and day sights rather than the Tactical's suppressor-height tritium night sights. Both share the same optics-ready slide, ambidextrous controls, and overall ergonomics.
The 10mm Auto cartridge has a well-established track record for backcountry use, offering significantly more energy and penetration than 9mm when loaded with appropriate hard-cast or bonded hunting ammunition. The 510 MRD's full-size frame helps manage that recoil, and the optics-ready slide makes it easy to add a red dot for faster target acquisition in the field. It's a legitimately capable outdoor sidearm, not just a range gun dressed up to look the part.
No, the FN 510 MRD does not have an external manual safety. It relies on the internal passive safeties built into its striker-fired design, similar to how the FN 509 and many other modern striker-fired duty pistols operate. For those used to running a Glock, M&P, or similar platform, the feel will be very familiar.
Yes. The FN 510 MRD is compatible with FN 510 Tactical magazines, including the 15-round flush-fit and extended 22-round magazines. This gives you some flexibility depending on your intended use, whether that's a more compact setup for carry or maximum capacity for home defense or range sessions.
The full-size polymer frame and 31-ounce unloaded weight help absorb a meaningful amount of the 10mm's recoil impulse. FN also engineered three distinct grip texture zones and a contoured grip frame specifically to help anchor the hand during recoil. The interchangeable backstraps allow you to optimize grip fit, which makes a real difference in how comfortable and fast follow-up shots feel with a hard-hitting cartridge like 10mm.
