About This Firearm
The FN 545 MRD is a full-size striker-fired .45 ACP built for duty use and home defense. It has an MSRP of $930, and each of its two magazines holds fifteen rounds. The slide is cut for a red dot and four mounting plates come in the case, so a sight goes on without a gunsmith.
The case also holds two interchangeable backstraps, a locking device and the manual, which covers most of what a buyer would otherwise order separately. This version has no manual safety, just a loaded chamber indicator, and FN sets the trigger at about 6 lb with the same pull on every shot. The grip stands 6 inches tall and measures 1.45 inches across to hold a double-stack .45, which is wide to conceal.
If you're cross-shopping, the Glock G21 Gen5 MOS holds thirteen rounds at 29.1 oz, runs a longer 4.61-inch barrel and ships with three magazines instead of two, although FN includes the optic plates and a case where Glock sells them by the model. The FN FNX-45 Tactical carries the same fifteen rounds but is hammer-fired with a decocker and a threaded muzzle, at an MSRP of $1,394.

Strengths & Limitations
- Four optic mounting plates in the box, so most common red dot footprints are covered at purchase.
- Two interchangeable backstraps change the reach to the trigger without any parts bought separately.
- The barrel is cold hammer-forged.
- No manual safety on this version, which rules it out for buyers and agencies that require one.
- The four plates cover the footprints FN chose, so an unusual sight can still need a plate ordered on its own.
- Black Cerakote over a machined steel slide looks plain next to a two-tone gun and will show holster wear at the muzzle first.
