It would be hard, you'd need a G20 probably, with a new barrel. Not sure if the extractor/ejector would work, but it might. Mags would be a problem as well, since the round I believe is too long for 9mm mags, and too skinny to use in 10mm mags.
I have heard of a 38super glock made on a G20, but I don't know all the details on it.
Some aftermarket metal mags might be more tunable to work with 38TJ
