Would definitely stretch the limits of the extractor to use 38 super with a 9mm/TCM slide/bolt and the casings might be off center enough that the firing pin may not strike the primer and fire reliably or feed into the chamber for that matter. Swapping barrel, mag and slide you may have a chance then getting it to work would be a neat gun to have 38 super in an A2 frame Probably won't get it done very cheap though. Good luck!
The .38 Super is a semi-rimmed cartridge. Replace the barrel with a bar-sto 38 super comp barrel. Starline has super comp brass which is rimless and feeds better- no rim to hang up. Use a Dillon press .223 shell plate. The 9mm, with the new projectiles is sufficient - if you want more velocity , re-chamber to 9x21, but consider the cost of brass. At the range where I shoot, I've picked up over 6,000 9mm cases, no 9x21 cases, two .38 Super cases, no .38 Super comp cases, and over 2,000 .223 cases that I make into .22TCM cases.
