    I carry 10 mm just wondering what other calibers I could interchange in my 20.

    .40,.357,& 9mm just have to buy the conversion barrels and a 9mm mag & a .40 mag you can shoot .357 rounds with a .40 mag. Also I have even shot 9mm rounds with my .40 mags with no problems.

    I'm not a professional please don't just take my word. I would check with a GUNSMITH first. :)

    A G-20 can fire 4 different calibers with the appropriate barrel; 10mm Auto, (obviously), .40 S&W, .357 Sig, and 9x25 Dillon. The standard 10mm mags will work with any of these calibers. Other caliber conversions are possible, but require replacing more parts.
