I used liquid Frog Lube on a Colt 1911 and it worked okay when I shot it regularly. However, the pistol would not run when I tried shooting it after a couple months of storage. The Frog Lube had turned waxy and slowed the slide travel. The Frog Lube fanboys will say that I used too much, or not enough, or it wasn't applied on a warm gun - none of which were true. I no longer use it on firearms and what I have left goes on knife blades in storage. It turns waxy on them, too, but I clean the lube off before use. IMHO, there are way better products out there.
