Guess That Gun

[garry_99]

How about this one?

[4INCHSMITH]

A 7.62X39 Deringer of sorts? No idea about a name though. Or is the ammo in the pic a red herring?

[HeroHog]

Dunno but now I want one!

[SDC]

Tricky, Garry; that's a Russian MSP ("malogabaritny spetsialny pistolet", or "compact special pistol"), chambered for an internally-silenced version of the 7.62x39; these use a sliding cup inside the cartridge case to seal all the propellant gas inside the case, but still propel the bullet at a lethal velocity, the same way the US QSPR "tunnel weapon" did.

Here are a couple of other rarish oddballs:

[SDC]

No guesses on any of these?

Revovler is a UDAR

[SDC]

Yep; the Udar (Russian for "Punch") fires a shortened 32-gauge (about 50 calibre) shotshell loaded with rubber, blank, or stun loads, but Tula also makes a smaller-framed version chambered for 9mm Makarov in moonclips, as the R-92. All of the others, except the top one, are also Russian, as a clue.

[Gary L. Griffiths]

Bottom one is a belt-buckle pistol. German, I think. IIRC, had 3 or 4 barrels, maybe 7.65mm (.32 ACP).

[rburch]

Isn't the top one of these that russian underwater ak? No clue what the name of that thing is.

ASM-DT Underwater Assault Rifle - Wikipedia, the free encyclopediaThe ASM-DT is a Russian folding-stock underwater firearm. It emerged in the 1990s.

Giat developed a family of small arms based on a 5.7 x 25 mm cartridge in the late 80's before this project was cancelled in favor of the FN P90 (which was in a later development stage). The project “Armes de Défense Rapprochée” (ADR) was to connsist of a semi-automatic pistol, a self-defense weapon (this one) and a small assault rifle. The project "Armes de Défense Rapprochée" (ADR) was to connsist of a semi-automatic pistol, a self-defense weapon (this one) and a small assault rifle. GIAT claimed four times the effective range and one third of the recoil impulse in comparison to 9 x 19 mm for their 5.7 x 25 mm cartidge.

The magazine was in the rear grip. Most interesting was the possibility to use it in a shoulder stance with the fore grip and trigger and as a classic submachinegun in confined spaces with the use of the rear trigger and the fore grip only as a grip.

Seems as if it had a grip safety at the rear grip and probably a magazine release catch, too. Seems as if it had a grip safety at the rear grip and probably a magazine release catch, too. It can also be guesssed that it used closed bolt operation because otherwise the emphasized range potential of the cartridge could hardly be exploited for lack of accuracy.

In the doctored photo isn't that a gun you only shoot once?

[SDC]

Herohog and rburch got theirs right; the "Morskoy Lev"/"Sea Lion" interchangeable underwater/above water rifle, that will fire either 5.45x39 or 5.66 Dart rounds, and the GIAT PDW, but the one that looks like a belt-buckle gun is actually a "cigarette-case pistol", designed by Igo Stechkin, the same guy that designed the APS Stechkin machine-pistol; it's also chambered for an internally-silenced 7.62mm cartridge, and was known as the "TKB-506A"; he also made another version as the "TKB-506", with a more conventional-looking trigger (below, in this photo of both designs together):

[Buffalo Wing]

The doctored, backwards facing revolver: I've occasionally heard it referred to as a "Smithsinski & Wessonowski". "New Polish target pistol, only fired once!"

P.S. I apologize if the Polish joke offends anyone. The first person I heard that from was Polish.

I hope these silenced 7.62 rounds are downloaded a little, out of those Itty-bitty guns? OUCH!
