Same here. I went down a P239 rabbit hole a couple years ago... Found a duo tone P239 in .40 with a .357 sig barrel w correct cal mags. I'll have to dig it out.I also got the 357 Sig barrel for my .40 P239. That is fun to shoot.
i am pretty sure I have one of the 9mm around here also. I did the same thing for the P229.
