A friend of mine, who owns a gunshop recently imported some Sportowy pistols along with their subcaliber (steel) cartridges. He gently sent me a sample
These adaptors were discussed here before
Anyway, I wonder why they didn’t produce an insert identical, in its outside dimensions, to the 7.62 Tokarev cartridge (the insert doesn’t chamber in a Tokarev pistol) . Why did they don’t simply made a 22 version of the Tokarev pistols? Maybe they found out simple and cheap to use original Tokarev slides and frames?
