I like Sig pistols. I have a P228, three P225's (all 9mm), a P239 and now another P239 both in .40 S&W. I believe I will put the .357 Sig barrel and mag in this one and leave it that way.
What a great pistol, I love the sig two tones. I also recently bought a 239 in .40, with the intention to convert to .357sig, and 9mm, but I think I will keep my 3913 as my 9mm since they are so close in size. I bought the 357sig barrel from sig last week they had a 20% off one item sale so I jumped.
