First Look: FN Big Bore Pistols, FN 510 Tactical & FN 545 Tactical


NEW from FN comes two big bore pistols! The FN 510 Tactical and FN 545 Tactical are chambered in 10mm Auto and .45 ACP, respectively. The FN 510 Tac comes with an industry-first 15-round standard capacity and 22+1 extended capacity of 10mm, and the FN 545 Tac carries 18+1 of .45 ACP.

Both are styled after the FN 509 Tactical, featuring threaded barrels, optics cuts, and suppressor-height sights. 

“There has been significant interest from FN owners in pistols chambered in big bore calibers over the last several years,” said Chris Cole, Vice President of Sales and Marketing for FN America, LLC. “We are excited to announce the release of the FN 510 Tactical and 545 Tactical pistols, chambered in 10mm and.45 ACP, that advance our flagship striker-fired line of pistols and complement our FNX-45 Tactical and FN 509 Tactical.”

“We pioneered the Tactical feature set in the FNX-45 and FN 509 Tactical pistols, introducing the industry’s first pistol that shipped from the factory with a threaded barrel, optics mount and extended capacity, and until now, the FNX-45 Tactical had the highest capacity of any .45 ACP pistol available from the factory,” said Chris Johnson, Senior Product Manager, Pistols, for FN America, LLC. “This expansion into new, big bore calibers has been a longtime in the making and we are excited to offer these pistols with this unprecedented capacity – 18+1 in the FN 545 Tactical and 22+1 in the FN 510 Tactical – along with the features our customers seek in an FN Tactical pistol.”

MSRP is $1,139 for both pistols in all color and capacity options.
