you don't need metal kit to run 1911(or MEU) on propane. Propane will give your more power(on blowback and fps), but it'll probably cost you on efficiency. With extra power and such it'll cause more stress on the gun and metal kit will make help in that respect(at even higher cost on efficiency)
FYI, you can't get stuff from Evike if you are in Canada....guns or metal kits....
