Never fired FN FNX-40. I purchased new, and it has been in my safe for a few months. It comes with a transferable lifetime Davidson's warranty.
.40 S&W, DA/SA operation, 3x 14 round magazines, external extractor with loaded chamber indicator, ambidextrous safety/decocking lever, ambidextrous slide stop & operation levers, 3-dot sights, 4'' hammer-forged barrel, front & rear cocking serrations, ergonomic polymer grip with 4 interchangeable backstraps w/lanyard eyelets, integrated MIL-STD 1913 accessory rail, owner's manual, and fitted hard case.
I will ship by your preferred method from my FFL to your FFL. I estimate the shipping and transfer fees to be approximately $50.
