I have an Xfive in .40 and I'm wondering if I can use my X5 40S&W mags for 9mm if I get a barrel conversion? I know this works with a few other guns, Beretta 92, some HK P series etc.
9mm in a 40S&W P226 X5 mag?

Yes. It works for the sig 226. You get benefit of sqeezing a few extra bullets in there.
The .40/357 mags are a hot comodity for that reason. I infact mall ninja' d 3 mags myself today. It was awkward when another guy came in right after me and saw what i had in my hand at the till which is what he came for too. He claimed for ipsc or whatever. I just bought em for explicit purpose of mall ninja-ing. Plus they were $10 cheaper then ive seen anywhere else. im not sure if i did a bad thing or not.

That's awesome news. I've got around 10 .40 X5 mags and really didnt feel like buying more.

Great that you got one opinion, but I'm to understand you own .40S&W magazines already? Try it out.
The usual problem with 9mm in a .40 mag. is that the feed lips are a little too widely spaced to reliably retain the slightly narrower cases (about a millimetre less in diameter at all points).
Load up your mag.s with some nine, see how many fit. Then try smacking them a little on the bottom and on the side, see if the rounds fly out under pressure. Then you can remove the barrel from your Sig and put the loaded mag. in, cycle it and see if it's stripping the rounds and not trying to double feed. You're ahead of the game on people who have to order the .40 holders and hope they work. The final test is, of course, at the range when you've got your calibre conversion.
Any modification done to the magazine in order to shoot more than 10 rounds makes it a Prohibited Device. This is because it is no longer as designed for the .40S&W cartridge, so the fact it holds only 10 of those doesn't matter. Technically you should be able to very, very slightly adjust the lips so that it will still reliably work with .40, and it will work better than stock with 9.
