Has anybody heard of any .25 ACP to .25 NAA (or similar wildcat) conversions? i.e. rechamber the existing .25 ACP barrel. A new magazine would obviously have to be made or adapted (and frame modified). I was thinking along the lines of rebating the rim of the .25 NAA to .25 ACP size. I own a robust little CZ92 chambered for .25 ACP which would handle increased pressures. Your opinions please.
