Design and purpose

The FN 545 MAGAZINE (15-ROUND) represents FN America’s full-size, double-stack approach to the .45 ACP—built for duty, defense, and high-performance training rather than everyday concealed carry. The platform uses a polymer frame with striker-fired internals, delivering the modern ergonomics and trigger characteristics that instructors and professionals expect.

Key features to know

This package is configured with three magazines and a soft-side carry bag, and it ships complete with FN optics mounting system and plates plus an owners manual. The optics-ready slide accommodates low-profile red dot systems via FN’s mounting solution, allowing shooters to leverage faster target acquisition during drills. Ambidextrous controls and thoughtful ergonomics help manage recoil and support high round-count sessions.

Caliber and shootability

Chambered in .45 ACP, this platform delivers proven stopping power and a broader frontal profile compared with smaller calibers. For duty use and defensive scenarios, .45 ACP offers desirable terminal performance; training with a full-size, high-capacity pistol lets you practice realistic follow-up shots and malfunction drills without compromising on ergonomics or sight picture.

Why the FN name matters

FN is a legacy brand known for military and law enforcement reliability. The FN 545 MAGAZINE (15-ROUND) sits in a premium product line, and its feature set—optics-ready slide, double-stack 15+1 capacity, polymer frame, and ambidextrous controls—reinforces its role as a full-size service pistol for professionals and serious competitors. The listed price of $699.99 reflects that positioning.
