Silent stalker I would not be so bold as to suggest a single product for everything. I dont think anybody (except a fan boy) would do such a thing.
An old revolver, A ML, A shotgun, A 911, An AR-15 or all the other firearms all all a bit different and I dont know if there really is one product that will do everything for any gun. As I posted in the final thoughts, if you are happy with your current product, dont change a thing.
That said, I will be using more Hornady One Shot on my weapons than the other products I had been using. But at time I will use the frog lube and for longer term gun storage (and certainly on a host of tools and outdoor applications) I will use the WD 40 specialist.
