Use Duster or HFC 134 or mix duster and green together. but dont use propane unless you get a reducer. the suggestion of using green or propane in the summer is deadly and can crack the slide.

Not if you get a metal slide :) Works fine for me, before I got sand in my gun :(

I purchased my USP Compact from jackson. ;)

Dont use propane stock though, you'll find that the slide catch and the slide will wear out very quickly, and you *can* break your frame, especially if you've got the Tiawan version. (cheap plastic).

I've upgrade mine with a metal slide, and recoil spring (amongst other things), and it runs perfectly fine on propane.

You need to remember to inspect for wear after every use, and lube it frequenctly with 100% silicone oil.
