Analysis

This .45 Auto pistol offers a robust design tailored for shooters seeking a full-sized duty or personal defense firearm. Its accuracy is commendable, delivering consistent performance at moderate ranges, thanks to a well-engineered barrel and sight system. Ergonomically, the grip provides a secure hold with customizable backstraps, accommodating various hand sizes, while the ambidextrous controls enhance accessibility for left- and right-handed users. Reliability is a key asset, with the firearm functioning smoothly across diverse conditions when properly maintained. However, maintenance can be somewhat intricate, requiring attention to detail during disassembly and cleaning. Availability of replacement parts may pose challenges in certain regions, potentially delaying repairs. The trigger pull is crisp, averaging around 5-6 pounds in single action, though some may find the double-action pull heavier than preferred. Felt recoil is manageable for a .45 caliber, though newer shooters might notice a pronounced kick.

Best Polymer Handgun Ever Built
By bassntwo on 04 Feb 2023
The best modern-day polymer handgun that has been built to date. I own a 9 mm with a stainless steel slide. When this FNX first came out I wasted no time in purchasing. I don't carry just any gun. Before this FNX I carried a 1911. I took this FNX to the range and before I cleaned it even the first time, I put 1,500 rounds down the tube, took it home cleaned it, and put another 1,500 rounds through it. Never hiccups, a jam, failure to feed, nothing. I have owned this FNX for 8 years and have over 15,000 rounds. I have shot every brand of hollow point and many different kinds of ball ammo. I am a licensed ammunition manufacturer, so I have also put a lot of hard casts lead down the barrel with a Brinell hardness of 10. Absolutely no leading of the barrel. I do take excellent care of all my firearms. I have had this one on my hip as my everyday carry outside of the waistband and a nice custom-made leather holster. This FNX will eat anything you put in it.
