I think that the decision to sell or not to sell is made by the gun shops. My gun shop and range sells it. I've seen it at other shops in the area. Maybe the reason many don't sell it is like a lot of other products in this internet age. When you can buy it with a click at Amazon.com for 30% less and have it in 2 days, most buyers do that instead of their LGS. I'm assuming you were talking about Amsoil and that Amaoil is a typo, I'm not sure if that's a good analogy. (not going to get into that "discussion" and I'll leave my opinion about that to myself

) I started out with Hoppes many years ago, then I discovered Breakfree in the early 80's, recently I've started using Froglube. Technology changes, if I find something that I think works better, I'm not trapped by "tradition". I now shoot a half plastic pistol, something I wouldn't have imagined me doing only a few years ago.
