Great Pistol. I am very satisfied
First off, Grabagun did a great job as usual sending this fast! Great service. I love this 45acp the best. Never had an FNH gun before. Love the manual safety. Good trigger. Low recoil, accurate. I put about 700 rds through with all kinds of ammo, no problem. I wish the back straps were smoother, hurts my palm. I am getting some sandpaper. I will be buying the 9mm. Can not go wrong

Great professional service and prices. Great and easy web site
wow, Was I surprised at the quality of the FNH-FNX-45. felt great in my hand. I wish the back strap was not so rough, but in the long run, it does not matter, I cleaned it before first shooting. Very clean from factory, just need some oil. I shot 150 rd of different ammo, no problem and good grouping. I wanted it because of external safety.Grab A Gun was professional and got back to me immediately to answer my question. Fast shipping. Great price. I have bought many guns and other stuff from them. I am going to buy another gun from them when it is back in stock.

Grabagun has very quick shipping on firearms. This 45 has a very minimal recoil. I absolutely love how this gun fires as well as it being highly accurate. Everyone should buy one of these pistols.

One sweet pistol
Grabagun shipped this gun very quickly, and the process was painless. This is my third FN pistol, and like the other two, this one is great from a fit and finish perspective. I put three magazines full of lead bullets through it today, and there were no issues at all. It is very accurate, and the recoil is much less than other 45's that I have fired.

FNX-45 15 Rounds
This is a great high capacity 45 ACP handgun. Just ordered one in black a few weeks ago and could not wait longer to get the FDE one. Very reliable on my first day shooting it.

Very impressive!
First off, Grabagun did a great job sending this fast! Great service and a great product at a great price! Now as far as the Fnx goes.....AWESOME! Recoil is very manageable and more accurate then my glock 21 with two more rounds then the 21. Great buy!

FN FNx Review Video

Compare FN pistols, see specs and models: FN 509, FNS, and FNX.



The FNX-45 is the result of years of innovative product development and advanced engineering techniques. Modeled after the FNP-45 service pistol introduced in 2007 under the U.S. Joint Combat Pistol Program, the FNX-45 is a double-action/single-action hammer-driven pistol with highly enhanced ergonomics. Its manual safety/decocking levers, slide stop lever, and magazine release are all fully ambidextrous for ease of operation with either hand and from any firing position. Both the slide and barrel are stainless steel. The FNX-45’s checkered polymer frame has multiple interchangeable backstraps with lanyard eyelets. A MIL-STD-1913 mounting rail on the underside accepts tactical lights and lasers.
