    While looking at Sigs, I became aware that you can change barrels to shoot a different caliber round. However, I am also under the assumption that the transitive property does not apply.

    True or False?

    A 9mm Sig cannot be converted to a .40 and .357sig but a .40 and 357 can do all three providing the barrel is replaced.

    If so, I would expect problems with jamming due to parts within the pistol that are meant for the .40 caliber but are obviously being used for a different size round.

    Thanks in advance.......

    My understanding is that a 40/357 Sig will shoot 9mm with a 9mm barrel and magazine. I have two 40 Sigs and I got 357 pipes for both of them but I am skeptical of the 9mm conversion though I have no reason to doubt it works.

    I got the p226 classic in 2lr and the sig upgrade package says 9mm 357sig and 40s&w for both the 226 and 229 price is 399.95

    Interesting,(all based on the 10mm) the .40 is a 10mm cut down, the .357Sig is a .40 necked down, so this Sig breach face is 9mm also.

    Kinda a scarey.........
