S&W Mk22 Mod 0 "Hush Puppy"

[Thisdale]

Greets everyone,

I'm looking for statistical information concerning the S&W MK22 Mod 0 Hush Puppy (frequently used by Seals during Vietnam i'm told).

When i search on google, all i get a very limited number of hits on "mk22 mod 0".

So i'd like to make sure this is what i'm looking for since i never actually saw this particuliar model IRL.

Here's the hit i get:

Mk22 Mod 0


Anyone has valid information concerning this pistol?

thx

Rather confused...

More photos would be nice too (especially with the Vietnam era SEALs).

Second pic is a relatively new Ruger Mk.II .22lr heavy slabsided barrel, made within the last 5 years or so probably.

[andrew_rsa]

didnt they call them hushpuppys because the seals had to use them often against guard dogs?

[Thisdale]

Yup, exactly right.

Thisdale, I have some info on the "Hush Puppy" but before I transcribe it from the book I would like to know exactolily what it is that you are looking for. Are you looking for stuff like the number of rounds in the magazine or more like muzzle velocities and the like?

Thanks

Hey Tunnal,

Actually, everything you got would be great... and perharps even info on that book of yours.
I'm looking for the usual stuff:

Caliber
# of rounds
Length of barrel (With & without Silencer)
Weight of Weapon (empty)(With & without Silencer)
Internal Velocity(With & without Silencer)
External Velocity(With & without Silencer)


And at least a good quality picture from both sides if possible.
As much info as possible would be welcome!

If its easy for you, a simple scan of the book's page would do fine, i'll scavenge that stuff myself and save you the trouble.

Thanks for your help!

The slide lock is on the left side.

All right here it is:
During the Vietnam conflict, the US navy sponsored development of the silenced pistol for use by its SEAL teams. Nicknamed the hush-puppy because of its intended function of killing enemy watch dogs, this modified version of the steel framed Smith & Wesson model 39 pistol was put to other clandestine used as well. Called the mark 22, mod. O pistol by the navy, the hush puppy had a slide lock to keep the mechanism closed and silent while firing. It fired a special green tipped 9mm parabellum projectile weighting 10.2 grams (158 grains that yielded a muzzle velocity of 274m.p.s. (900 f.p.s), below the speed of sound. Use of standard supersonic ammunition quickly degrades the effectiveness of the silencer insert. With subsonic ammunition, an insert is good for about 30 rounds; with standard velocity cartridges the insert may have to be replaced after six shots. Official navy designation for the silencer is mark 3, mod.0 . Ammunition and replacement silencer parts are supplied as accessory kit MK26, Mod.0. Each accessory kit includes 24 9mm pistol cartridges MK144, mod.0 and one silencer tube insert.
All the work on the model 39 hush-puppy was carried out by Smith & Wesson before the end of 1968. Subsequently, Smith & Wesson provided two prototype 13-shot pistols made from stainless steel. These weapons were improved to overcome problems such as extractor breakages, which had been experwnced with the model 39. This modified pistol in a slightly different form as later commercially marketed as the model 59 Smith & Wesson 9mm parabellum pistol.

I hope that this is helpful to you… sorry I don’t have a scanner there are a some interesting photos of the weapon and how it all fits together as well as with and with out all its attachments.

I thought this was a fictional weapon because the first time I heard it was in MGS3 Snake Eater when Snake is given one of these, but good find.

[Merit]

I think the Japanese site is correct with M39 besides the rear sight & the slide stop. BTW, anyone has pic of the slide stop & how it actually works on the MK22 Mod0?

[Thisdale]

Wow thanks a whole lot Tunnal, this is great stats!
Taking note of the book as well, will try to pick it up!
