SKU: FN 66-101709-845737017392
Built for shooters who want a duty-oriented 9mm pistol with suppressor and optic compatibility, this mid-size model combines a 4.5-inch threaded barrel with an optic-ready slide and suppressor-height 3-dot night sights. The flat-faced trigger and striker-fired, semi-automatic action support a clean, modern setup for range work or defensive use, while the Flat Dark Earth polymer frame keeps the profile consistent across the pistol. It ships with five magazines, including both 15-round and 24-round options, along with a ballistic case and two backstraps for fit adjustment. The package is well suited to users who want a configurable handgun without adding aftermarket parts right away.
