About this product
The FN 502 Tactical .22 LR 4.6″ Threaded Barrel is a slide-mounted, optics-ready rimfire pistol that delivers FN ergonomics and controls in a rimfire package. Built for training, high-round-count practice, and general range use, this pistol pairs rimfire economics with tactical-style features. The steel, threaded barrel (1/2×28) and optics-ready/serrated slide accept low-profile red dot sights, while the polymer frame with integral Picatinny rail and ambidextrous controls ensure familiar handling.

Key Features
- Optics-Ready Slide: Serrated slide with direct-mount footprint for low-profile red dots means faster target acquisition and precise shot placement without bulky adapters.
- Steel Threaded Barrel (1/2×28): Factory-threaded for suppressors or compensators, giving you stealth training or reduced recoil right out of the box.
- Ambidextrous Controls: Slide stop and magazine release are mirrored on both sides, so lefties and righties run the gun the same way under stress.
- Integral Picatinny Rail: Mount a light or laser for low-light drills or home defense practice without aftermarket adapters.
- FN Ergonomics & Controls: Grip angle, trigger reach, and control placement mirror the FN 509 series, making this a true trainer for duty-sized pistols.
Who It's For
This pistol is for shooters who want a rimfire trainer that mirrors full-size tactical handgun ergonomics. If you run an FN 509 or similar striker-fired pistol for duty, competition, or home defense, the 502 Tactical gives you the same controls and feel at a fraction of the ammo cost. It's also for suppressor enthusiasts who need a reliable .22 LR host with a factory-threaded barrel.
Pros & Cons
- Pro: Optics-ready slide with multiple mounting options – no need to send the slide out for milling.
- Pro: Ambidextrous controls make it truly lefty-friendly.
- Pro: Threaded barrel from the factory saves $80-150 over aftermarket options.
- Con: The trigger has a bit of creep and a long reset compared to aftermarket triggers; it's serviceable for plinking but not competition-grade.
