Wishbone has it right. Check out Sentry Products Armorer's kit. For about $30, you get a Tuf-Cloth, some Tuf-Glide (thin film lubricant; dries to touch in seconds), some Smooth-Kote, which is molybdenum disulfide with an isopropanol carrier; use on hammer / sear / trigger surfaces, also Sentry recommends coating bore (NOT chamber) with it; claims to eliminate fouling and leading. Also included is a powder for application to sear / hammer / trigger areas; supposedly decreases friction another 20% or so.
I am going to try this on my 1911's. Walt
