    I have a G20 sbr (Kpos) in 45acp, 10mm, 9x25 Dillon.
    I want to ad 357sig to the combo.
    I see conv. Bbl's
    But how do the mags work? What mag could I use?

    Edit: I wrote 40s&w when I should have written 45acp.

    If you're already shooting 40 S&W?
    The 357 Sig is a necked down 40.
    The case size is basically the same.
    The 40 mags will work with 357 Sig

    357/40 mags have different followers.
    But for the range it doesn't matter.

    For SD, maybe? Maybe not. Opinions vary.

    The G20 is wider than the 40 & 9mm frames. The 357sig G31 & 40 G22 mags will not fit-

    Can I use a G20 mag?

    don't have a G20, but if you are using the G20 mag to shoot 40 S&W, you should be able to run 357 Sig with the G20 mag also.

    Thats just it. Can a G20 mag safely feed a 40s&w or a 357sig?

    The latter bullets are shorter than the 10mm-

    Yes! A G20 mag will feed both .40 and 357sig safely and effectively!

    Question.

    Answer.

    I love my G20 and have been wanting to get a 9x25 Dillon conversion barrel for it ever since I got it. Haven't yet, but will some day. :cool:

    I just emailed LWD for a G20 to 357Sig 8" or 10", they have a 6" already but I want more!
