If anyone is interested Tomster over at SIGForum is getting together a Barsto barrel purchase...these will of course fit all SIG220 and P220 STs 4.4" and 5.5 "
$170 and $182.75

That's not a deal. Barsto will discount their barrels 20% to any valid FFL holder. Just ask an FFL holder to receive one for you, that's what I did. Most will without any markup.

For replacing a damaged or otherwise unservicable barrel, I would think Bar-Sto.
But just for the sake of change?
That much to be gained over a factory barrel Vs. cost?
After all we are talking Sig here.
And supposedly, a stainlees barrel didn't "work" in a P220ST, the factory opting for a carbon steel one after finding out the SS ones jam in the SS slide and frame.
Just thinking out loud here...
