FN 509 vs Water: Will It Fail?
This comprehensive test evaluates the FN 509's performance against water submersion compared to a Glock 17 Gen 5. The FN 509 exhibited significant reliability issues, including dead triggers and slide lock-up, after being submerged. The Glock 17 Gen 5, while not entirely immune, performed considerably better under the same conditions. The findings suggest the FN 509 may not be ideal for maritime environments where quick deployment after water exposure is critical.
