When you choose a defensive sidearm, you’re betting on your training, your mindset, and the tool in your hand. In the city, you need something fast and confident. In the backcountry, you need a pistol that won’t blink if the trail gets loud. That balance—urban precision and wilderness authority—is where this 10mm shines.
FN 510 MRD steps into that role with purpose, pairing a proven 10mm Auto chambering with the familiar ergonomics of FN’s 500-series pistols and a slide cut for optics from the start.
The 10mm Auto Advantage
10mm Auto has a reputation: decisive energy, deep penetration, and performance that bridges everyday carry and the outdoors. For personal defense, it delivers authoritative terminal ballistics when you need clean, controlled stoppage. On the trail, it stands up to tough tasks—where you might encounter bears or other predators—without asking you to trade controllability for power. In a full-size platform tuned for the cartridge, follow-up shots stay manageable, and that matters when seconds count.
This pistol channels that energy intelligently. The slide mass and overall balance help tame recoil impulse while keeping the sights honest during rapid strings. If your defensive world spans parking lots and pine forests, 10mm done right gives you one handgun that makes sense both places.
Optics-Ready From the Factory
The milled slide comes ready for red-dot duty—no gunsmith invoices, no guesswork. You also get four optic mounting plates in the box, which means your favorite footprint is likely covered. Mount, torque, confirm zero, and get to work. Suppressor-height sights ride tall to co-witness through most micro red dots, giving you a clean iron backup and a faster dot pickup under pressure. If you’ve ever lost a dot in a bright wash or low-light movement, those taller irons are the lifeline that keeps your cadence steady.
That setup matters for both concealed carry and field carry. A crisp dot for speed, iron co-witness for verification—stacked redundancy that’s easy to trust when your heart rate starts to climb.
Ergonomics You Already Understand
The frame brings the familiar feel of FN’s 500-series pistols. If you’ve run them before, this one falls into the hand naturally. Two included frame backstraps let you dial in grip size to your wrists and draw stroke, which means faster acquisition from concealment and a more repeatable grip under gloves. The all-black finish is all business—no shine, no distractions—exactly what you want on duty, in the truck, or under a jacket.
Capacity-Compliant, Mission-Ready
This model ships with two 10-round magazines, keeping it compliant where capacity limits apply without stripping the pistol of its 10mm purpose. For the trained shooter, 10-rounds of 10mm with efficient reloads is more than a plan—it’s confidence you can carry. The magazines seat positively and feed reliably, and having a matched pair in the box means your sustainment training can start on day one.
EDC to Backcountry Without Compromise
As an everyday carry pistol, it fits the role with its optics-ready slide, capable cartridge, and practical controls you can run under stress. As a trail sidearm, it earns its keep with 10mm authority and suppressor-height sights that stay visible through mud, mist, or the rain beads on your optic. FN Herstal built this one for real work—calm in the city, unafraid in the woods.
Transport is straightforward thanks to the premium zippered case included in the kit. It’s a detail that sounds small until you’re moving from range bag to truck to safe and want your setup protected. Stash your spare magazine, optics plate, and tools—everything has a home so your system stays squared away.

Training Notes from the Range
Run your dot at a brightness you can hold through daylight and transitional shade—then confirm iron alignment with the suppressor-height sights. The 10mm’s recoil is honest but manageable; focus on strong support-hand pressure and lock your wrists. Work cadence drills until your dot settles naturally where your eyes want it. For the backcountry, confirm point of impact with your chosen load at defensive distances and a bit beyond. Confidence isn’t loud—it’s consistent.
Who This Pistol Serves Best
