I have used it on my carry XDS-9 and on my 10/22 takedown. I have had no problems with either both have fed and shot reliably. The stuff works as it should and cleans easily. It also is easy to apply and doesn't stink. It is expensive for the little bottle but a drop of the stuff goes a long way. I like it better than Froglube.
I have been using it for a few months now. Love it. Had our annual cleaning of our 4H guns last weekend and cleaning went faster than ever. We soaked down the worst of them and let them sit while working on the ones that we're not as bad. Most of these guns have multi thousand rounds through them between cleanings and we just wiped the carbon off. As far as price, it's a little high bit if you follow them on Facebook the run special codes occasionally to help a little.
