Cheapest online price for P320 Sub-compact is $495 (Sept. 2018) before the transfer fee. X-Change Kit is only $314. You'd save $181 - minus $45 for extra mag. This kit has everything you need to convert compact to subcompact model. It even has the SIG factory night sights. Only con is that the kit only gives you one mag, but it's a minor nit-picking. Works flawlessly out of the box. Unless you need to use both compact and subcompact pistol at the same time, this is a great, cost-effective option for having both compact and subcompact handgun, depending on your needs. However, the goofy thing is, the subcompact guns is as heavy as the compact model and the subcompact slide is only slightly shorter than the compact slide. Thus, it doesn't do much for concealed carry as much as one would expect.
