Lone wolf used to offer such barrels.  If you aren't familiar, look at 9X25 too.  It is the 357 sig's big brother like the 10mm is to the 40 S&W.

Bar-sto offers excellent barrels and catalogs M20-357 sig barrels.  They are a bit spendy though

The Glock will accept a barrel chambered in 357Sig and 9x25 Dillon, however the 357 Magnum case is too long as loaded. but the 357Sig easily will make the 357Mag powerlevel with some bullets.  9x25 can match and even exceed those levels.

Holy crap, 100mm will have some major recoil issues. Let me calculate. The recoil spring will need to be 8 feet long and 65 lbs.  :)) :))
