I'm not talking about oil manufacturers I'm talking about gun manufacturers talking about oil, they have what they use in house and they have what they sell. They go through a lot in house. I also happen to know that some agencies have been talked into snakeoil, to their detriment, on numerous occasions, wasting thousands of dollars, risking lives, and ruining guns, all in the pursuit of the latest and greatest lube. Their budgets for the training department could have used that money much more effectively had they not bought into the stupidity, ammo and more time on the range. Which actually for some departments, is important, as it should be. Most modern muni forces in Canada actually have significant training budgets for firearms, and they are pushing for more, because that's the one area that has been lacking for years, and weapon maintenance is a part of that budget. To suggest that they are on the range "playing" with guns is idiotic and shows a complete lack of understanding of what their job entails, or why they are on the range training. But hey, what do I know, I've only done contract work for a bunch over the years and regularly consult with them still. But that is completely unrelated to the topic at hand, and as demonstrated in this thread alone, there are people buying into the snake oil too. Advocating for products that cost 100 times more than a bottle of motor oil at Cambodian tire.
We all get the fact you hold yourself up as an expert among the tactical group, consistently consulted by the major police forces in Canada and regularly advise police agencies across Canada on how best they spend their limited funds on lubes. I am also painfully aware we have gung ho officers out there feeling the restraints of not being able to use their blasters as effectively as they might want to. That said, the OP asked a question regarding lubricating his handgun.
To him most lubricants will do. If he cleans his gun after every range sessions as a lot of folks do a small bottle of gun oil will last him/her a very long time. Most are convenient to use and don't take up a lot of space on the bench. If you are a shooting a lot and think you need a quart of motor oil on your bench that will likely last most shooters two lifetimes run with it.
If you are working for a Municipality and happen to be the purchasing agent and also might be reading this thread buy motor oil it comes n convenient 45 Gallon drums your officers will thank you for it.
