The new Glock handgun cases are a tremendous step up, but I would contend the G40 has outgrown it. Opening it up, the case nearly popped out due to the contents. Everything will go back into the case, just make assured to brush up on one’s Tetris skills.

Overview & handling

I expected the Glock to be onerous considering its size, but it was a gentle giant at just over 28 ounces. Now, I would not call it graceful, even for its size. Unloaded, the pistol is front-heavy from the long-slide, but upon addition of the magazine, it starts to balance out (about 40 ounces). It’s not until the red-dot is on the top that I found it suitably vague for extended shooting sessions.

The grip itself is massive. Those with small hands need not use, even without the back-strap. My wife, who can fairly hold a medium back-strip G17 9mm found it difficult to get a firm grip & reach the trigger simultaneously. My medium-sized hands found the smallest setting most convenient, but the medium back-strap most promising, as I tend to grip high on a gun & get slide-bitten. Unlike another Glock competition-oriented handguns, the G40 does not have the extended slide stop.

I am sure it will be mentioned a few more times, but for handing ideas, its a glock 40 Gen 4. The glock 40 Grip holds finger groves (which work for me), the square textured grip pattern (which I also like), more significant & reversible glock 40 Magazine release, & a too shallow undercut on the trigger guard for the middle finger. It arrives with standard flexible glock 40 Sights (which work, but are terrible) & interestingly, the rear sight projects the back of the slide a bit. Not sure if this is an engineering oversight, but its annoying for “perfection.”

GLOCK’s website lauds the G40 MOS as “the ultimate opportunity in semi-automatic gaming pistol.” When RF handed me the case, I looked at the box & thought, “Well, they sure aren’t wasting money on packaging.” Gaston’s mob stuffs the 28 oz. Long slide powerhouse into the equivalent cheap, bursting-at-the-seams plastic case they use for all their handguns. Opening it revealed a jumbled block of backstraps, mounts & screws, arranged with all the organization & presentation excellence my three-year-old would muster.

The firearms farrago added a pack of base plates. Like the FNX-45 Tactical, the G40 MOS (Modular Optic System) design lets buyers mount a range of pistol optics on the slide with no more trouble than squeezing a few screws. So I added Trijicon’s ever-popular RMR, a combination highlighted in GLOCK’s product literature. Unlike the FNX-45 Tactical’s, the G40 MOS’ factory sights weren’t raised. They didn’t co-witness the RMR’s dot with the stock sights. Like, but not quite a perfection.

RMR on MOS, I was able to shoot. One problem: the three magazines supplied were conspicuously empty, & proved to be surprisingly difficult to fill. In a shocking reversal from my STI Nitro 10 review, I had plenty of magazines & no ammo. Cheap 10mm ammo wasn’t to be seen, so I shelled out the cash for 200 rounds of the better to excellent stuff. My supply combined HPR, two different Hornady loads, & some DoubleTap ammo. Lesson learned, again, for the third time: if I choose a 10mm for my perfect truck pistol, I’m reloading my own.

To the range!

The only Glocks that matched my hands well are the full-frame models, & this one was no different. The gun still doesn’t aim naturally for me, but man, the G40 MOS’ grip feels good. One-handed, I get a powerful grip all the way around the gun. The raised dots, the material itself & the finger grooves gave me a solid lock on the frame. This & a good rest made zeroing the RMR a breeze; I got ‘er done in six rounds.

Because the gun seemed so good in my hand, I put a few magazines underneath range one-handed. At 15 yards, right or left handed, this G40 MOS is the regular shooting of the higher powered pistols I’ve ever shot. Shooting right-handed, one shot per second at 15 yards on a 5 ½” plate? Easy. & that’s with a 10mm handgun. I don’t shoot this fine one-handed with my Wilson Combat WC92FS in 9mm.

What disqualified the FNX-Tactical from the truck gun contest – my search for a gun that can ethically harvest game & conceal carry around town – is also a problem for the G40. On 1911, a 6” slide looks long. On this GLOCK, it looks like a harpoon over the trigger guard. The large frame is already difficult to conceal; that runway-length slide does it almost impossible. Almost.

I do a bit of leatherwork & I mocked up a few holsters for the glock 40 Holster. With a light jacket & the right cant, the 10mm GLOCK is reasonably concealable. But – hidden like that, I’d never been able to draw it when seated. & not quickly from any position. That doesn’t detract from how well the gun made, but it does put it does make it questionable as a truck gun contestant.

I still think every American should own a Toyota Corolla & a G19 at least already in their life, just to see that “good enough” actually is pretty good. But the G40 MOS fires like a different beast altogether. It’s the first GLOCK I’ve shot especially well. If I can figure out a way to holster it, it will have taken the STI Nitro 10’s place as the front-runner as my co-pilot.
