I've liked FN firearms since I was in basic training and first got the opportunity to get behind what may be my favorite gun of all time––-the M240B. Unfortunately, I can't have one of those in my personal collection so I've been collecting their handguns, rifles, and shotguns ever since. FNH makes great military and civilian firearms and I haven't been disappointed in any of them thus far.
The FNX line of pistols are decedents from the Browning PRO guns. Sales of the Browning Pro were disappointing so FN rebranded the pistols the FNH FNP and sold them under the FN name. Sales still were lower than expected so they 'improved' upon the original design and released the FNX (more on that in the video).
-Accuracy (in SA mode, this gun is extremely easy to shoot accurately)
-Reliability (I've never had a malfunction of any kind with this firearm)
-Durability (cold hammer forged barrel, stainless slide, ect...)
-MIL-STD 1913 rail for lights and accessories
-Comes with 3 magazines
-4 interchangeable backstraps
-Aftermarket support (holsters, parts, ect...) are availible
-Safety acts as a decocker as well
-The position/size of the safety/decocker rubs my thumb (and the thumb of others that have tried it) when firing high round counts
-Mag lockup is suspect. I've never had an issue with it but it doesn't inspire confidence either
Here's a video with some shooting, table top review with disassembly/assembly and size comparison with other popular pistols, and some chronograph testing.
