When I bought my first SIG fourteen months ago, the SIG dealer told me to use Militec-1. I'm now up to nine SIGs, and I still use Militec-1 on all of them. Most of my new SIGs even came with a small bottle of Militec-1 in the box from the factory. The stuff doesn't evaporate like many lubes, and multiple applications gradually form a slick layer something like Teflon. I've read on other forums that our guys in the sandbox are asking family and friends to send them Militec-1 because it's far superior to the issued CLP in that environment.
