I’ve used a few different petroleum and synthetic lubes for my firearms the past. However, after sitting for a month or so I noticed my S&W .357 cylinder release button felt sticky, but after switching to Amsoil gun cleaner and lube, I can pull it out of the safe and the switch moves just as smoothly as when I put it away. I also noticed how dry the lube is and doesn’t attract debris and lint easily. I also noticed a perceptible decrease in trigger pull. The stuff is great! The product is high quality and using it gives a feeling of satisfaction knowing it came from good old USA grown ingredients. The owners of this distributorship are very responsive and helpful in selecting the right product for any application.
