More Information about the FN FNX-45 Handgun

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.

20 Round Mag for for the FNX Tactical 45

This Magazine works & operates just fine without any problems at all, as if it were made for this gun. The extended mag makes it a little more difficult for conceal carry but not sure it was meant for that.

It's Awesome Baby

My brother recently purchase the FN FNX-45 firearm and complained each time we are at the range because he had to reload constantly. The firearm came with a lesser round magazine. I didn't help my brothers situation since I have an XDM Elite with a 35round magazine. So doing range work was easy for me.

Anyhow, I went searching the Internet and came across the Promag FN FNX-45 45ACP 20 Round Magazine. I bought it immediately. I surprised him at the range when I gave it to him loaded. The mag immediately went through about 300 rounds that day no failures. It just worked fine all the time as expected. He is happy and I am happy. I plan to get him another one and surprise him again. He is very happy at the range with it. Can you all make an even higher round magazine, OMG he would just love that.

Thanks, you all nailed this one.
