510 And 545 MRD

FN America has announced 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 feature 15+1 rounds of 10mm or .45ACP at the ready, a target-grade six-pound trigger pull with crisp break, and the company’s patented optics mount. The 510 MRD in particular is sure to find favor among hunters, as either a close-range hunting pistol for medium-sized game, or a bear-defense sidearm in the backcountry.

“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,” said Chris Cole, vice president of sales and marketing for FN America, LLC. “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 provide a clear sight picture, allowing the user the focus on the red dot of the optic.

Included backstraps can be installed to adjust fit in the user’s hand, delivering  a natural point of aim and dampening felt recoil—especially valuable for the 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 designed for both control and shootability.
