This is a community dedicated to discussion around historical arms, mechanically unique arms, and Ian McCollum's Forgotten Weapons content. Posts requesting an identification of a particular gun (or other arm) are welcome.

Rules:

1) Treat Others in a Civil Manner. This is not the place to deride others for their race, sexuality, or etc. Personal insults of other members are not welcome here. Neither are calls for violence.

2) No Contemporary Politics Historical politics that influenced designs or adoption of designs are excluded from this rule. Acknowledgement of existing laws to explain designs is also permissable, so long as comments aren't in made to advocate or oppose a policy. Let's not make this a place where we battle over which color ties our politicians should have, or the issues of today.

3) No Advertising This rule doesn't apply to posting historical advertisements or showing more contemporary ads as a means of displaying information on an appropriate topic. The aim of this rule is to combat spam/irrelevant advertising campaigns.

4) Keep Post on Topic This rule will be enforced with leeway. Just keep it related to arms or Forgotten Weapons or closely adjacent content. If you feel you have something that's worth posting here that isn't about either of those (and doesn't violate other rules) feel free to reach out to a mod.

5) No NSFW Content Please refrain from posting uncensored extreme gore or sexualized content. If censored these posts may be fine.

Post Guide Lines

These are suggestions not rules.

-Provide a duration for videos. eg. [12:34]

-Provide a year to either indicate when a specific design was produced, patented, or released. If you have an older design being used in a recent conflict provide the year the picture was taken. Dates should be included to help contextualize, not necessarily give exact periods.

-Post a full URL, on mobile devices it can be hard to tell what you're clicking on if you only see "(Link)".

-Posts do not have to be just firearms. Blades, bows, etc. are also welcome.

The PSS-2, as the name implies is the next generation of the PSS design which was adopted in the 1980s. The original gun boasted the ability to be shot silently without a suppressor due to its special piston based 7.62x42 SP4 ammo.

In order for the PSS to achieve this it needed to use heavy cylindrical bullets to increase the mass to stay subsonic and avoid a supersonic crack. This resulted in the bullets preforming poorly against armor this is where the PSS-2 steps in. It put a wedge shaped tip on its bullets to maintain mass while reducing the surface area that'd touch the vest on initial impact to increase penetration.

7.62x43 SP-16 ammo for the PSS-2

The PSS-2 is a recoil-operated weapon that utilizes an open breech system and is mechanically similar to its predecessor, the PSS. Its unique design includes a mechanism that slows the slide’s movement in its final stages to prevent clanging noise.

I've always enjoyed these silent ammunition types.

This article on Russian silent ammunition used by the KGB is one of my favorites.

Wow TIL Johnathan Ferguson mentioned a derringer design in the last Q&A to a question I asked. I'm guessing it was one of those two. Definitely worth their own post.

I love the piston concept too such a change in functionality by simply adding one moving part.
