sub caliber adopter for Soviet 5,45x39mm cartridge

[RCS]

The Soviet PSM pistol chambers the 5,45x18mm and is quite rare to locate or purchase. Before the US ATF requirements went into effect (the PSM would not pass the requirement for import), there
were a few PSM pistols in the USA, some were gifts and some smuggled. One was on a west coast auction in 1993 listed for $3000.00, I saw a PSM on a small auction in the late 90's for $3400.00.

Note, you can make 5,45x18mm from 22 Hornet brass
