The 4.1 in non-threaded barrel is cold hammer-forged with a recessed target crown and a 1:16 RH twist, delivering durability with precise rifling. This setup supports dependable performance with .45 ACP while keeping overall length compact for a full-size slide.
The FDE slide features an optics cut with a cover plate, plus front and rear serrations for positive manipulation. Raised steel sights, with a drift-adjustable rear, are sized to co-witness with MRDs for a clear, usable sight picture.
Ergonomics center on control and adaptability: the pistol is striker-fired with a trigger safety, and it includes an ambidextrous slide stop and magazine release. Interchangeable backstraps and the polymer frame’s texture support a consistent grip.

Overall length is 7.7 in, height 6.0 in, and width 1.45 in, with FDE finish across slide and frame. Made in the USA by FN America in Columbia, SC.
