You really can't over lubricate your gun. Some people will say yes you can; because the powder residue, dirt, etc... will attract to the oil and can create sludge and gunk; thus impeding proper mechanical actions. Well; in theory, yes. In reality; most people clean their guns after each use at the range. Therefor, the amount of lubrication on the gun when it's put away after being cleaned, isn't going to be picking up any dirt, residue, powder blast, etc... Also; when the time comes that you need the gun for self defense; it's very unlikely that it's after firing 500 rounds at the range where it collected a lot of residue powder, dirt and dust collected to the oil. It's after it's been cleaned and then lubricated. Therefor, a clean gun with a lot of oil on it, is not going to cause a problem with the 1-7 bullets you're possibly going to shoot in self defense. The excessive oil isn't going to make the bullets feed from the magazine poorly. If it's a revolver, it will do even less damage. The only time too much lubricant can be a problem is when it's in an area of the gun that's going to collect powder residue, carbon, dust, and dirt from shooting it. But for a self defense situation where the gun has been cleaned after the last time at the range, the excess lubrication isn't going to hurt anything.
