Thanks for that link Cluttonfred,
I know that take-down AR-15 rifles are popular with American wannabee warriors, but I question their usefulness in the hands of a battered, bruised, cold, wet, disorientated pilot who narrowly survived being shot down. Re-assembling a rifle is a complex process that must be practiced on a regular basis.
In a perfect world, the barrel and receiver would be hinged together for a quick, night-time, unfold and twist together process.
At a minimum, I would recommend some sort of loose link that would keep the barrel and receiver in loose formation to A: prevent them from getting lost and B: to simplify the process of alignment and assembly.
And that's not the only interesting thing about it.
Don't think that was the APS. I believe you're talking about the TP-82 survival gun that was used on the Soyuz capsules. Tri-barrel with one 5.45x39 and two firing a specially-made 12.5x70 shotshell (which comes out to 40-gauge), with a beefy e-tool/machete similar to a Woodsman's Pal for the stock. Was developed after an incident where the Voskhod 2 capsule (who were returning from the first-ever spacewalk) landed about 250 miles from the intended drop point, in the back-end of nowhere and ended up stranded for two rather chilly nights in the taiga. The Voskhod kit had a Makarov and a supply of ammo, but understandably the cosmonauts weren't too confident about potentially using it on the wolves and bears found in the area, and once they were recovered Alexi Leonov suggested developing something with a bit more utility.Dear Cluttonfred,
Military pilots have been issued a variety of small pistols that fit better in cramped cockpits.
The Soviet Stechkin APS was issued to Soviet pilots and Kosmonauts for a while. It was chambered in the usual 9 x !8 or 9 x 19 ammo, but featured a wooden holster that doubled as a shoulder stock. The shoulder stock was similar to that issued with Mauser 9 or Inglis Browning High-Powers.
More amusing was a Stechkin variant that substituted a Woodsmans Pal edged tool substituted for the shoulder stock.
