For example, some people like to grease the rails instead of oil them on a 1911-A1...or all new SIG rifles come with a sample tube of TW-25B grease as if you MUST use it? There seems to be two opposing positions on gun grease because it attracts crud, but I just need to know whether to use it or not on the affor mentioned examples or other guns, or scenarios when grease is a must. Seems like it might be useful for break-in at least, but right now I am leaning back over in the no-grease camp and would like to ONLY use it on parts and firearms it is a necessity.
Thanks!
