I used to clean and lube with CLP, and never had a problem. Then I switched to lubing with LP on exposed areas (1911 slide rails, barrel link, etc.) and a graphite/moly engine assembly grease on closed areas (mainspring, hammer/sear). Still no problem. Now, I use Wilson Ultima Lube oil and grease for the specified applications, and . . . still have no problems. I do use the grease on the rails and barrel of my carry gun, to keep it in place long-term; but I think adequate lubrication is the key, more than what product is used for the lubricating. I read that some SAS guy dipped his Hi-Power in gin, as the the slight oil content of the berries used gin-making left a thin lubricant on the gun, without attracting a lot of dust. Hmmm, peanut butter sandwiches and gin might be a good shooter's diet!
