I bought a 9mm Sig Pro Sp2022 sometime in the past year or so.. Guy here is offering a slide with both 40 cal and 357 sig barrels for the early version Sig Pro 2340... I'll buy it from him if it will work on my later Sp2022 frame. Can the experts here help?

Yes, it will work fine, 40 and 9mm frames are identical

Update... received the 40/357 slide and barrels and it looks like everything is good... at least it fits and functions... have not taken the pistol to the range... might even later today... but now that I think about it, I don't think I've ever run 9mm through the 2022.

the only problem I have is I had to take the foam out of the bottom of the factory LEO case that was included with the slide, barrels and magazines to get it all in with the original 9mm mags and slide....
