    I have a 9mm barrel for my 40 XDM and got a lot of "why don't you just buy the 9 in the first place" comments also. Guess what... I have one of those too.
    Next question.

    The XDM conversion requires a conversation barrel though, I've been told by a few sources that just swapping factory barrels from one gun to another doesn’t work.It may be different for the XDS.

    I wouldn't be surprised at all if 9mm and .40 used the same weight recoil spring. Between them, it's more about the weight of the slide dictating the necessary spring than the power level.

    .357 Sig is in the same boat.

    Yes the 40 has a wider diameter rim than the 9, so your extractor will be off using a Std 9 bbl in a 40. The conversion bbl is slightly off center at the base to correct this
