Gun of The Week, Jan 28th, 2013 MK23LAM

In this weeks segment, I am going to share something special. Special as in SPECIAL OPERATIONS. This is one of the pistols used in the Mark23 trails. It is H&K’s submission, that eventualy went on to win the contract.

If you have never held/handled a MK23, its about the size of a shoebox. It is the largest, most unwieldy pistol that I have ever held (besides a blunderbuss). My small girly hands could not operate the slide release or the saftey from a normal pistol grip. Here are some pictures including a size comparison with a 60MM Mortar.

The Box


Pistol with LAM (laser/light Aiming Device). It has red laser, IR laser and White Light if I remember correctly. Battery’s were dead so no idea.


With the H&K (?) suppressor submitted in the trails.

Had tritium night sites

This was right before I got yelled at for handling with no gloves…I’m like this shit was jumped,dived, and humped all over…It’s going to be fine.

And Lastly, Here is it next to a 60MM Mortar for size comparison.

Final Words. They guys at Crane and Navspecwar must have been high as a kite when they decided to procure this weapon. It is hard to articulate how large and unwieldy this gun is. Add to the fact that it only shot .45, it just seems like a waste of money and space, with no ballistic advantage to it’s size. Very cool gun, and I’m sure it had almost no recoil suppressed, I cannot think of a scenario where this would be needed. The HK tactical is 98% of the Mk23 and about half the size. Rumor has it that they have moved onto HK45’s and HK45CT’s.

Hope you guys enjoyed… Stay tuned for next week’s…

THE GUN OF THE WEEK!!!

I need an original LAM badly.

The suppressor was probably manufactured by Knights or B&T, they are the usual suspect when it comes to HK.

And sure it’s as absurdly big as a Desert Eagle, but you have to remember 20 years ago (fuck it makes me feel old to say that) this shit was cutting edge. HK was the first handgun with rails, Glock then evolved the design and finally somebody said to put a picatinny down there.

I still remember getting my first USP9 back in 94, still one of my favorites.

Very cool.

I got to handle a couple MK23’s a few weeks ago and was amazed at how huge they are. It would be completely impractical, but I really want one. Maybe some day…

There’s quite a few dead noisy dogs, and shot out bright street lamps in Iraq to confirm that the MK23 did indeed have practical uses.

I want a MK23 just to have one. That was the hot shit everyone used in movies and video games when I was growing up. Thanks for sharing.

I live and work near Crane. In the early 90’s, I think it was 93, a few of us got to to go Crane. We shot this pistol and Colt’s entry at one of the many indoor ranges there. Crane has a spectacular museum as well. We have been fortunate to be able to have Crane as a neighbor.

They didn’t exactly shoot regular old 230gr ball through it…

I always wanted a Mk23 but I kind of gave up on owning one when I sold my Wilcox LAM collection. The Wilcox Nightstalker LAM unit had some really neat features that you don’t see on modern units. The mounts themselves were sighted in rather than the laser itself. Also, the laser had several blink modes and the incandescent light could be dimmed.

I would love to hear about it’s operational uses(non sensitive obviously) if you would like to elaborate.

I am putting together a request from Crane and hopefully wiggle a trip out there to hand pick out some new pieces. Apparantley they have some MK11’s and 12’s that need a new home!

What did they shoot in it?

Crane made up 1400FPS ammo to include armor piercing, incendiary, and explosive… The gun is built to never break, if I remember correctly the two SEALS charged with testing the first two submitted pistols fired 25,000 PROOF rounds through each pistol and then used up another 20,000 rounds of +P ammo before one of them suffered a tendon injury and they halted the test. The gun is indestructible.

The Mk23 was called “the first crew-served pistol” in a Youtube video. :smiley:

I’m enjoying your “of the week” posts.

Not an HK question, but what is the spriral wrap around the tailboom of the mortar round?

I was informed by an SME here that it is also capable of firing partially submerged. :wink:

Having handled a few of these beasts I can say they truely are a large pistol. I can’t imagine trying to use one of those with that LAM and suppressor on it. Need a sling for that sucker.

I had a chance to shoot one a couple of years back.

Like the others have said, it’s huge. The “crew served pistol” joke definitely has some basis in reality. I think the only thing I’ve seen larger is when Jack Nicholson shot down the Batwing in the first Batman movie. On the plus side, very little recoil and very smooth shooting.

Thanks for the great series, I’ve been looking forward to these as they come out!

They’re called cheese charges. They act as the propellant. If you’ve ever heard a mortar crew giving commands like “Charge 2” or “Charge 3” etc, the number of cheese charges is what they’re referring to. The ones in the picture are probably just foam or otherwise inert.

Wait a few weeks and one of the segments will be on the Mk 1 Underwater Defense Gun. A prototype underwater revolver made for taking out enemy divers.

You know… they might call them cheese charges, but they sure dont taste like cheese…

Your 100% correct. They act as a booster to give the mortarman more range or increase the incline so a round can be dropped behind defalade.

The one shown is an inert training model. I dont think it was ever issued or used, as it looks brand new.

I really want a MK23 just to have one also. Glad to have been able to shoot one, but not suppressed sadly.
