FN Extends Line of Big Bore Pistols: FN 510 & 545 MRD

FN America, LLC is pleased to announce the release of the striker-fired FN 510 MRD and 545 MRD optics-ready big bore pistols. With dimensions just slightly larger than an FN 509, these two big bore pistols are ideal for users who want to carry with a lot more stopping power.

The pistols feature 15+1 rounds of 10mm or .45ACP at the ready, a target-grade 6-pound trigger pull with crisp break, and the company’s patented optics mount that enables enhanced accuracy, making them the perfect tool for personal and home defense. Harness the stopping power of these big bore calibers and be ready to face any situation that may come.

Following the overwhelmingly positive response to the FN 510 and 545 Tactical, which released in January, we received customer feedback requesting models in these calibers with flush-fit barrels, day sights and magazines that were more carry-friendly, as well as accessible in states that restrict threaded barrels or capacity. These MRD models, following the successful formula of the FN 509 MRD models, feature our patented optics mounting technology in a 15-round grip frame optimized for accuracy and shootability.

The FN 510 and 545 MRD feature a flush-fit, 4.1-inch barrel housed within a machined steel slide with front and rear cocking serrations for ease of manipulation. The barrels are cold hammer-forged with a recessed target crown to extend accuracy and a polished feed ramp to ensure reliable feeding of the majority of commercially available loads in both 10mm and .45ACP.

The MRD slide is equipped with FN’s patented Low-Profile Optics-Mounting System that accepts all major optics footprints and enables consumers to direct-mount nearly any optic in minutes with the included hardware while a set of fully adjustable blacked-out iron sights co-witness with most optics and are to provide a clear sight picture, allowing the user the focus on the red dot of the optic.

The impressive ergonomics and contouring of the 15-round grip frame deliver the perfect balance to the slide. The included backstraps can be installed to adjust the fit in the user’s hand to deliver a natural point of aim and dampen felt recoil, especially in 10mm. Coupled with the three distinct grip textures that all play a role in anchoring the pistol to the hand, the FN 510 and 545 MRD are extremely controllable and shootable big bore pistols.
