Lately, I am into weird calibers as well. I found a Colt gov't in 9x23 with .38 super conversion. In my recent reading and shooting these rounds, I love these hot 9mm's. They should have kept the .356 TSW over the .357 Sig. Makes alot more sense and the handloads seem to be smokin for the .356. Recently, I have been contemplating having my P226 fitted with a 9x21mm barrel. The 9x21 can be loaded pretty warm as well. Good luck.
