B&T GHM-9 Review: Is This the Best Pistol Caliber Carbine to Date? (4K UHD)


– [James] Hey guys,
James again, with TFB TV and I have a special treat for you today. It is the B&T GHM-9. The GHM-9 is B&T’s new nine millimeter pistol caliber carbine
and with a street price of around $1200, it’s taking aim directly at the SIG MPX and the slightly
less expensive CZ Scorpion. The scorpion and the MPX are definitely the two most dominant non-AR- nine millimeter pistol caliber carbines. So, how does GHM-9 stack
up and is there any room in this crowded market for it. Before we get there, put
on your tin foil hats because I’ve got a conspiracy theory. I’ve told you guys this before, my wife, Lindsay and I
are two big nature nerds, so, when I disassembled the
GHM-9 and I saw this engraving in the upper receiver,
I knew something was up. That’s a mouse eating a
scorpion and I’ve watched enough BBC documentaries to tell you, that, that is a grasshopper mouse. These cute little bastards eat all kinds of insects, including scorpions. Grasshopper mouse, GHM, scorpion killer, you do the math. The GHM-9 is a nine millimeter blow back, pistol caliber carbine
and although it uses a straight blow back recoil system with a closed bolt, the
GHM-9’s bolt carrier group has a hydraulic buffer
in the rear that really does dampen the recoil. It’s recoil impulse is
closer to the milder shooting MP-5, because of the
hydraulic buffer system. The GHM-9 uses the same
polymer lower as the APC-9 and the same magazines and
if there’s at least one trait that the GHM-9
shares in common with the MPX, it is that the
magazines are 70 bucks. It has an ambi mag release
and an ambi bolt release as well as an ambi thumb safety. The aluminum upper receiver
is totally monolithic and it has full length, 12
o’clock rail and 6 o’clock rail along the bottom of the
free floating hand guard. Also, note the screws on
the outside of the receiver towards the barrel, those
go directly into the barrel trunnion, so, the user
can change the barrel at home. Unlike the MP-5 it has a
last round bolt hold open and another really cool feature is a reversible charging handle. I want to give a big shout out to the St. Bernard Indoor Shooting Center for letting me film this
video at their range. So, in return I’ve let
the guys at St. Bernard shoot the gun, but only
if they would let me put them on TFB TV. So, as you’ll see, here,
Cam is demonstrating how if you’re a right hand
shooter, that reciprocating charging handle that’s
attached to the bolt can sometimes get in the
way of your support hand. So, what’s your option? Flip it over to the right hand side. That might make charging a
little bit more cumbersome if you’re a rightie,
so, you’re going to have to charge it AK style, however, again, it has an ambidextrous bolt release, so, if you’re trying to
execute a quick reload all you gotta do is press a button. You don’t have to worry
about flipping the gun over on it’s side and pumping it manually. As you can see, the lower attaches to the upper via two pins. So, field-stripping
the lower is very easy. The pins are captive,
you just knock them out, just like in AR-15 and
speaking of just like an AR-15, I’m fairly confident that the GHM-9 is using an AR-15 or at least,
AR-15 style trigger group because it looks and
feels almost identical although, the trigger pull on the GHM-9 is slightly smoother and
slightly better than the MPX, which I know for a fact,
uses an AR-15 trigger group. I should also, mention that Geissele, has a trigger for the GHM-9 on the way. Now, if you see that 3rd
pin all the way to the rear, I thought that was kind of
silly looking, at first, however, it’s pretty ingenious. The two pins allow you to remove the lower and you can also, remove
just the top pin to take out the recoil springs and the
bolt for a quick cleaning. As you see here, I’m a
complete and total idiot and it is very difficult to remove a stock and the stock trunnion at the back without the recoil assembly shooting out the back and it’s not that big of a deal. Speaking of the stock,
you’ve seen this B&T minimalist stock on quite a few other guns and for nine millimeter
use I am a huge fan. It’s incredibly lightweight and it’s still a very comfortable wire stock. That said, I wouldn’t be butt
stroking anyone with this stock and while I do like
the MPX stock, slightly more, and I do believe the MPX stock is going to be much more robust, than the folding stock and the GHM-9, the GHM-9 is extremely low profile, extremely lightweight and
very quick and easy to deploy. Giving it a slight edge on
the MPX collapsible stock. We shot a few hundred rounds
to this gun and universally, everyone who shot it, absolutely loved it. It’s nice. It’s definitely a scorpion killer. – [James] The bottom line is the GHM-9 is on par with
the MPX if not better. Although, they both have
their pluses and minuses and I certainly think
that the GHM-9 is better than the Scorpion and while the GHM-9 generally,
drips with Swiss quality, I mean, you really feel it when
you pick up this svelte gun. There were a couple of
minor issues that I could see as being easily fixed
that caught my attention. First of all, the thumb
safety, while, they’re easy to manipulate, tends to dig into the webbing between the webbing between your thumb and your index finger,
if you have larger hands but that’s something you
could really mill down yourself if you needed to. Second, I was actually kind of pissed off about the stock retention system. By the time I received this brand new gun, it wasn’t even working. So, we had to shoot it
with the stock deployed, the whole time, which kind
of defeats the purpose. B&T explained that they imported a bunch of TP-9 stocks for the
GHM-9 and installed them on the prototypes, but
they found out they’re not an exact fit from
the TP-9 to the GHM-9. Future GHM-9 stocks are
going to be custom fitted, however, this gun is still evolving. It’s still relatively new in the market and they’re still looking
at making minor changes here and there to the GHM-9, in order to make it the perfect
pistol caliber carbine. B&T and third parties
are presently working on brace adapters for the GHM-9. B&T sent me their own
Swiss made SMG-9 suppressor to use on the GHM-9 and as
you can hear in this video, sound suppression was very
impressive, even indoors. I’ve got a video review
coming on DSMG-9 suppressor once I break it out of jail and I get to use it on a few other guns. Note that B&T actually
makes H&K OEM suppressors. So, in conclusion, I have
to say that the GHM-9 is almost perfect and I
think it has the potential to be the best pistol caliber
carbine on the market. But before anyone can say
that with any authority, it’s gonna need some
time on the market to see how the reliability plays out and to see it evolve into it’s final form. Anyways, I want to say
thank you to you guy’s usual for watching, thank
you to Ventura Munitions for sending me the ammo
that we used through the B&T and thank you to B&T for
sending me this gun to evaluate. As an epilogue, I was so
impressed with the GHM-9 I decided that I’m going to be buying it. I’ve done the paperwork
on it and hopefully I’ll have it in a few
months and we can do a true side by side comparison. Guys I will see you next week. (upbeat music)

  1. So, its the "scorpion killer" but you have to magwell grip it or flip the charging handle over or get bitten, has a crappy stock retention system and costs more? I'll stick with czechnology.

  2. I just figured out the G H M thing the other day while driving I knew about the grasshopper mouse eating the scorpion and it was taking aim at the Evo 3 but didn't realize until then even the name is Grass Hopper Mouse 9

  3. Yeah… I’ll stick with the Scorpion.

    -Swappable charging handle.
    -Non reciprocating charging handle.
    -Price (MSRP and street).
    -CZ has great LE/Mil discounts
    -$20 mags.
    -About the same 1913 space available.
    -Just as compact, especially with OEM stock.
    -Great sight system.
    -For the same price of the B&T you could have a Scorpion SBR with stock kit and tax stamp.
    -Looks way nicer.

  4. Twice the cost of the CZ, though. The numbers in the header are not accurate. They are sold on Atlantic Firearms together and that’s not including the insane price for the magazines. CZ wins.

  5. No one ever wants to mention the $400 sub2000 when they review a B&T. Also "comfortable wire stock" is a contradiction. Also, that is a lot of gas in your face. As a Mac owner I can tell you that wouldn't fly in full auto.

  6. You need to do a B&T GHM9 pistol vs the Grand Power Stribog 9mm pistol.  They look very close to being the same firearm yet a little bit different looking.

  7. "New pistol caliber carbine" So… a big piece of waste? Look at all the metal and plastic and for what? Just to fire off some dinky little 9mm out of a pistol length barrel?
    Why not just use a B&T MP9?!?! Why make a new design instead of iterating or improving the MP9? Why not just make an MP9 version with a longer barrel or supporting 10mm or something? They already have a 9mm carbine– oh wait, the MP9 is smaller and wastes less space than this huge monstrosity and it's not even a blow back design and is therefore superior!
    This is just so dumb.

  8. This reminds me of your galil vs ak-47 video. More refined , yes, but at 25% more of a cost, not to mention the cost of mags and aftermarket parts. Don’t get me started on the sigs cost lol

  9. Yay it uses APC lowers. That means i can run the new glock conversion kit @ $500 and its still cheaper than an APC.

  10. Are there any configurations of the B&T that can take Glock mags, 9mm? and is there a nicer folding stock that can be used, that locks in place? one more thing, what model has the 1/2×28 threads, along with the other 2 options asked about? great video guys, I may have missed a few things though. I had planned for a zenith, but I think I like this better, at least for the cost. I just wish they would do something to eliminate the reciprocating charge handle. AWESOME, I LOVE IT WITH SOME IMPROVEMENTS….longer barrel option too, so I dont do something stupid, I see James in there with his fingers pretty close to the end…dont love that part. Otherwise, a great alternative to the zenith.

  11. I have a CZ Scorpion and would love to own this too but it's street price is like double that of a Scorpion and $70 mags? Gross.

    You aren't killing any Scorpions with a $2000 price tag and $70 mags.

  12. Did you ever make that side by side review of the GHM9 and the MPX/Scorpion? If not, please do it!

  13. As a Brit who lives in a country where the average person thinks all guns are capable of full-auto- EVEN I can see that a reciprocating charging handle on a pdw is a dumb idea

  14. Man i want one ive set my mind this is gonna be my next weapon may take me a year and a half but ive set my mind im gonna get one
