Same hereI use a light dab of Tetra on my 1911s, and while it does get a little dirty, its never gummed up the works. I used to use automotive grease (lucas red and tacky) but gave TetraGun a try, and could feel a noticeable difference in how the slide racks and the gun functions. If its a polymer pistol I use CLP.
