Been shooting 1911s since 1976 when I started into IPSC with series 70 Colts. Never used grease on a 1911 and never will. I've never known anyone that used grease on a 1911 of various makes and models. I still own and shoot several and no grease.I need some recommendations for some good gun grease, for the slide and rails on semi auto handguns. 1911 in particular. I used to use a red grease that came in a syringe. It was good and easy to apply, but I don't even vaguely remember the brand of the name. I've looked around, but have found nothing even close to what this used to be. Thanks in advance.
