After an 18-month wait I finally had my cataract surgery in January. One of the downsides was that I didn’t have quite as much near-focus vision as I’d had before…not that much less, but enough that regular pistol sights were a little more out of focus for me. I’ve been using reading glasses for the past year or so so it wasn’t a huge change, but it was enough that it gave me the idea to try a pistol with a compact optic. I’ve been using red-dot sights on my black rifles for years, but I hadn’t tried a handgun with one. I picked up a couple of second-hand Trijicon RMRs, and both a Glock 17 MOS and FX FNX 45 Tactical from a couple online gun shops. I figured the Glock would be quite familiar to everyone, but the FNX maybe less so—I had never even seen a newer-gen FN pistol like their FNP, FNX or FNS lineup until mine showed up. Here are some thoughts after the first week.

I picked up the FDE model—the appearance of the colour varies a fair bit depending on the light from almost an olive colour to a caramel brown. The “Tactical” version of the FNX varies from the regular version, I think, by having a longer (5.3” vs. 4.5”) barrel, higher “suppressor” night sights, and a slide pre-milled for compact optic mounting.

It’s a full-size pistol for sure—the normal cap magazines holds an impressive 15 rounds of .45 ACP so it's disappointing to be limited to ten here. I was apprehensive about the grip size but it’s surprisingly manageable—the extra capacity is achieved not by increasing the grip’s girth but by having a grip that is longer than other comparably-sized pistols. The grip circumference is only 14.5cm (5.7"), just a bit more than the 9mm Glock 17 at 14cm (5.5"). It’s a very manageable grip, even with my small hands.

The grip has raised grooves on the front strap and a bold pyramid-like texture on the side. I like the grooves—they let your fingers slide into a good grip easily while still providing a solid purchase. The pyramids feel, to me, more or less the same as a Gen 4 Glock…maybe a bit more aggressive.

The only grip customization is changeable backstraps. What’s neat is that in addition to two different shapes (straight and curved) you have a choice of textures (grooved or pyramids)—I don’t know if any other pistols have this feature.

I’ve got the straight-backed pyramids on mine. (Is that a lanyard loop at the bottom?)

The FNX is a DA/SA pistol with a combination safety-decocker. The safety can be applied with the hammer down or cocked. It’s not quite as positive-feeling as the safety on an H&K USP, and there’s not as much of a “stop” when sweeping the safety off before activating the decocker…it feels to me like you might inadvertently decock the pistol under stress. The slide release is a Glock-style nub that’s protected by inadvertent activation by some protrusions. I prefer a larger-to-activate slide release myself. It seems that smaller slide releases might be becoming more common—my SIG P226 Legion has a similarly small one. I guess the modern thing to do is the slingshot slide release but I prefer a slide-stop release. The rear suppressor sight is significantly higher than the normal sight. The bore axis is quite low, too. I'm not a "low bore axis at all costs" guy, but all things being equal, a low bore axis is better.

Controls—even the mag release—are ambidextrous. the mag release is your typical push button release, not a H&K or Walther paddle-style one (which I would have preferred).

The trigger is smooth and there are no humps or grooves inside the trigger guard (I hate those on the HK45 or SFP9). There’s a molded-in overtravel stop on the trigger (but what’s funny is that there’s still significant overtravel after the break).

Here’s a quick demo of the trigger pull—I like it.


The front sight is, of course, tall as well. A thread protector is included…this would be an awesome pistol for a suppressor (if we were allowed them)!

Here’s the sight picture through the RMR (I always find it hard to get a picture that represents what your eyes see). The high sights do cover a fair bit of the RMR window. I guess that since they co-witness I should be able to zero the sight more easily. I’ve heard that seeing the sights means you can locate the red dot more easily but I’m a little dubious as to if that’s a worthwhile feature. I’d prefer, I think, if they were shorter.

There are robust-looking rails inside the frame for the slide to run on.

There’s a plate on the top of the slide that you remove to reveal the drilled and tapped holes for the various optics.

An RMR-compatible plate and screws are included (not like Glock that make you buy the screws separately. The same screws are used to mount both the sight and plate.

The mags are a little odd—instead of having a notch in them there’s a small lug on the front the the mag body that engages the mag release notch. I’ve had it fetch up on the release a little a few times when inserting the mag…I’m a little concerned it could sometimes be an impediment to a smooth mag change. All three mags had the same brazed area—it must be part of the pinning process to limit it to 10 rounds.

Disassembly is easy—lock the slide back, unscrew the thread protector, swing the disassembly lever 90°, retract the slide a bit then ease it forward. The guide rod is steel (and the mainspring quite stout).

The pistol comes with a really nice case with room for extra mags, the extras mounting plates and even a suppressor (which I’m using for the trigger lock)


So, what do I think? As fas as regular DA/SA polymer pistols go I think I prefer the H&K USP—the trigger pull is a bit better, and the safety has a more positive feel (and I prefer the USP’s slide stop and paddle mag release). The trigger pull on the FNX is a bit lighter, if I remember correctly, and the FNX’s grip is more manageable. I do like the ease of mounting an RMR (which is why I bought it in the first place). If we were allowed normal cap mags 15 rounds would be awesome, too, as would suppressor use. As for other polymer .45s, I like the feel of the FNX better than the Glock 21 (which I find a bit large in the grip) and the HK45 (which I always found too slippery in the hand, plus the damn trigger guard groove bit my finger under recoil. I'm pleased with it so far.

With a foot of snow on the ground and another expected early next week I expect it'll be some time before i get to the range—I'll update the thread once I'e had a chance to shoot the pistol.
 
feels to me like you might inadvertently decock the pistol under stress.

That is actually my single biggest complaint with this pistol. Not that I have ever accidentally decocked, but that my standard "thumb over the safety" grip could lead to inadvertently decocking.

The one I've played with has 15rd magazines and a SilencerCo Osprey but no RMR. I like it but it is hard not to think of it as the tacticool polymer equivalent of a gold tiger striped Desert Eagle.

Good detailed write up. I hope you enjoy shooting it.
 
Great review. I've had my older FNP Tactical for about 5-6 years and simply love it. Of all the safety-decocker mechanisms, I actually like FN's version. I haven't found inadvertent over-travel going from SA cocked and locked to decocker without concerted effort. My only complaint is that the molding is pretty aggressive on the grip. It's a solid pistol and mine should finally get a suppressor added later this year.

Very nice review! Thanks!
I personally think it has an amazingly smooth trigger, and I think you will find the recoil fairly tame. Quite a few friends have shot my tactical, and all have had positive comments about it. It's really hard to find anything negative about this pistol.:thumbup:

I think the co-witnessing is mainly there in case of a washout, which really is a thing under certain lighting conditions. Here's a video by Ian McCollum where he discusses the topic (somewhat long - 15 minutes, sorry - please forward to 6:45 where he discusses the importance of co-witnessed irons):

I recently purchased the FNX as well. I've shot several 45's and this is by far my favorite. The recoil is much more manageable with standard factory ammo in my opinion. The low bore axis and heavy spring do their job. The long trigger travel up front doesn't impress me, but it is built for tactical operation in the field. If your considering the purchase, I don't think you'd be disappointed. I chose this over a kimber and springfield 45. I'd do it again. Great write up, I agree with everything you posted! Shoot straight, and stay safe.
 
I finally had a chance to take the FNX45 to the range today. I only had an hour to try out three new guns so I was a little pressed for time. Even this short shake-down, though, was enough for me to really appreciate the pistol.

I started with my usual “out of the box” test for a new pistol—10 rounds at 10m at a brisk pace (the first clip in the video below shows this string). The first thing I noticed was how mild the recoil was—my last two polymer .45 pistols were a GLock 21 Gen 4 and an H&K Mk23 and the FNX was noticeably milder in recoil than those two…surprisingly so, even. Having the co-witness sights made my at-home sight adjustment pretty close—I was pleased with this first group.

I tried a few more magazines-full with no problems and finished off with five rounds at 25m. I was feeling a little rushed and I am pretty well out of practice—I haven’t shot at this distance since last fall and I haven’t been shooting at in in more than two months so I know this group is not representative of the pistol’s potential but I’m OK with it. The slide did not lock back on the last round for the final string, although it did when I racked the slide. This was the only issue with the pistol.

Here’s a comparison of the dot sizes for the 9MOA RMR on the Glock and the 3.25 MOA on the FNX (the black aiming mark on the target is 4.5” and the distance is 25m. The large dot on the Glock did not bother me—I'm not planning any long-distance shooting with the, and the green really stood out.



I enjoyed shooting this pistol very much—the recoil was a pleasant surprise and the trigger pull was easily managed, too (although there was one shot where the longish reset caught me up a little bit…it’s at the 17 second mark in the video). I had my RMR-sighted Glock 17 MOS out for the first time as well and I must say I enjoyed shooting the FNX better. Despite it being a .45 I was able to track the dot better though recoil than I was with the Glock. I’m not sure if the it was because the co-witnessed sights help re-orient me faster or because the Glock’s snappy recoil jumped the sight around. There was a few times that the Glock’s window came up that I did not know here the dot was. More shooting with both I think will help. In my earlier post I mentioned that the sights seemed a little distracting but at the range the were much less noticeable. Overall I am really pleased with the pistol.

 
I really like this pistol but it seemed the girth of the grip was larger than usual for a double stack 45 so I did not buy it.
 
Thanks for the kind comments. This is one of those guns that ends up being better than I expected...for me, most times guns have lived up to what I expected of them, and a few times they've fallen short but it's such a pleasure when one exceeds expectations.
 
I unexpectedly had a chance to go to the range for a bit this evening—I only had 21 rounds of .45ACP in the house but I didn’t want to pass up the chance to try some 50m shooting. I was short of time last range trip and didn’t get to try the pistol at longer distances. More time, less ammo tonight!

I checked when I got home and found that I haven’t fired a pistol at 50m since my last competition in 2011 so I am for sure a little out of practice! I tried the one superfluous round into the sand backstop just to check on the sight’s zero—it looked to be pretty close.

I tried three groups of five rounds from the prone position—the longish grip and rounded mag basepad made it easy to rest the pistol on my shooting mat. I was pleased with the pistol’s performance—the trigger pull seemed to be even longer than before, but it was manageable.

Here’s the best group:

I put each new target over the previous one for each five round group—once I was done I removed the final two target— here are all 15 rounds from the three groups. I'm pleased!

This was the first time I’ve used a pistol-mounted sight at any distance past 25m—it really made it easy to get a good sight picture. I was surprised at the results—even being way out of practice I was shooting the FNX about as good as I’d ever shot a handgun at 50m—maybe better!

I finished off with the final five rounds quickly at 7m as fast as I could pick up the dot just to get that slow shooting out of my system. :)

Dragonfly, that's a pretty doggone good group at 50m! I haven't mastered my beast as well yet. I've pumped quite a few rounds through mine already. Not a hitch other than the slide not locking open on occasion as you mentioned in your post. I absolutely love this pistol. It eats everything and shoots just as well at steel with cheap ammo as the hand loads.

Thanks! I was really pleased with the pistol's performance.
