Key Features
- Low-Profile Optics-Mounting System — This system uses a guarded slide cap and includes adapters for RMR, Holosun, and Docter footprints. WHY IT MATTERS: You can mount your preferred red dot without buying extra plates or sending the slide to a machine shop.
- Gray PVD Slide Finish — The physical vapor deposition coating resists corrosion and wear better than standard nitriding. WHY IT MATTERS: The finish holds up against holster wear, sweat, and field use, keeping the gun looking sharp for years.
- Threaded Barrel with Thread Protector — The 4.71-inch black steel barrel is threaded (1/2×28) and comes with a protector installed. WHY IT MATTERS: You can attach a suppressor or compensator without buying a separate barrel, saving you $150–$200.
- Interchangeable Backstraps — Three backstraps (small, medium, large) let you adjust grip circumference. WHY IT MATTERS: A proper grip fit improves recoil control and shot-to-shot consistency, especially with hot 10mm loads.
- Integral Picatinny Rail — The polymer frame has a full-length MIL-STD-1913 rail. WHY IT MATTERS: You can mount a weapon light or laser without adapter brackets, keeping the setup slim and secure.
Who It’s For
The FN 510 Tactical is for shooters who want 10mm power in a duty-ready semi-auto. It fits hunters who need a sidearm for bear country, competition shooters who shoot major power factor loads, and tactical users who run suppressed or compensated setups. If you own an FN 509 and want the same ergonomics in a 10mm, this is the upgrade.
Pros & Cons
- Pros: Optics-ready out of the box; threaded barrel included; gray PVD finish is tough; reliable with full-power 10mm ammo; FN’s proven striker-fired trigger.
- Cons: 10-round magazine capacity is lower than some competitors (e.g., Glock 20 holds 15). The grip texture is aggressive — it can chew up skin if you carry concealed without an undershirt.

FAQ
What optics fit the FN 510 Tactical without adapter plates?
The slide ships with adapters for RMR (standard and RMSc), Holosun 407C/507C, and Docter/Noblex footprints. You can also use the guarded slide cap if you run iron sights only.
Does the FN 510 Tactical come with suppressor-height sights?
Yes. The front sight is a green fiber optic, and the rear is a serrated black notch. Both are tall enough to co-witness with most red dots mounted via the low-profile system.
Can I use 10mm loads over 1,200 fps in this pistol?
Yes. Per FN specs, the 510 Tactical is rated for all SAAMI-spec 10mm ammunition, including full-power loads like Buffalo Bore and Underwood. The barrel is 4140 steel with a 1:16 twist.
Is the FN 510 Tactical compatible with FN 509 holsters?
Not directly. The 510 Tactical has a different slide profile and rail length. Use holsters specifically molded for the FN 510 or universal-fit holsters with adjustable retention.
What is the trigger pull weight on the FN 510 Tactical?
Per FN’s published specs, the trigger pull is 5.5–6.5 pounds. It’s a striker-fired design with a clean break and short reset.
