gun oil/CLP range shooting...
In general, I give my firearms a quick pass of Ballistol or CLP before I go shooting on a range. It lubes the moving parts & aids cleaning later on.
As I posted, don't use a lot of oil or CLP. A few drops is all you need.
Professional gunsmiths & LE armorers who attend gun company seminars all say improper cleaning or using a lot of gun oil are some of the biggest problems.
