Sten SOE/CISA Silencer Ratchet Plate Details

That's a lot of holes! Does the muzzle end get a deep counterbore? Seems with that much bleed-off the bullet might not make the end of the barrel...

Peter notes it was to reduce bullet speed to subsonic, and that the CISA unit was very nearly silent from 40' (yards? can't recall) away.

Yes...that's a lot of holes. I assume the drill press operator got intense psychological counseling after completing each barrel.
