Key Features
- Threaded, Target-Crowned Barrel (4.71 in) — The barrel is threaded for compensators or suppressors and target-crowned for improved muzzle stability, so you can mount accessories without losing accuracy.
- Optics-Ready Slide with MRD Plates — The slide is pre-milled for micro red dots and includes multiple mounting plates, letting you add a dot without sending the slide to a machinist.
- Ambidextrous Controls — Slide stop and magazine release are mirrored for left- and right-handed shooters, making this pistol accessible to any student or shooter in a class setting.
- Tritium Night Sights — Three-dot tritium inserts provide a visible aiming reference in low-light conditions, critical for defensive or training use after dark.
- Integrated Picatinny Rail — A full-length rail under the barrel accepts lights or lasers, so you can build a duty-ready or home-defense setup without adapters.
Who It’s For
This FN 510 Tactical is built for shooters who need a reliable 10mm platform for personal defense, backcountry carry, or competition. If you’re a new shooter stepping up from 9mm and want more stopping power, or a seasoned instructor who needs a gun that runs with both standard and high-capacity magazines, this fits. The 15-round flush mag and 22-round extended mag give you flexibility for range training or field use, and the ambi controls make it a strong choice for left-handed students.
Pros & Cons
- Pro: Factory optics-ready with multiple plates — saves you time and money over aftermarket milling.
- Pro: Threaded barrel is standard, not an add-on, so you start with suppressor or compensator capability.
- Con: The double-stack 10mm frame is wider than single-stack 1911s or Glock 20s, which may be an issue for shooters with smaller hands.

What is the barrel twist rate on the FN 510 Tactical?
Per FN USA specs, the barrel has a 1:16-inch twist rate, which stabilizes standard 10mm bullet weights from 155 to 200 grains effectively for defensive and target loads.
Does the FN 510 Tactical come with a suppressor height front sight?
Yes, the factory tritium night sights are suppressor-height, so you can co-witness through a red dot or use them with a suppressor attached.
Can I use the 22-round magazine for concealed carry?
While possible, the 22-round extended magazine adds significant length and weight, making it better suited for range use, competition, or open carry/chest rig setups.
What holsters fit the FN 510 Tactical with the threaded barrel?
Most full-size 10mm holsters with an open muzzle or threaded barrel channel will work, but brands like Safariland and Bravo Concealment offer models specifically for the FN 510 series.
Is the FN 510 Tactical reliable with all 10mm ammunition?
FN recommends a break-in period of 200 rounds of full-power 10mm ammo (not reduced loads) to ensure reliable cycling. After break-in, it runs consistently with most factory loads.
