I tried it on several guns. At first I thought it was going to be great because it was dry and didn't attract dust. One was my 45 M&P duty weapon. That's a gun that never, ever failed. I followed the instructions to the letter. I detail stripped the gun and de-greased it. I then warmed it with a hair dryer and and applied it. Of course it melted over everything. I wiped it off like the instructions said. I even heated it again twice and wiped it down again. You could not see or feel it on any parts. About 100 rounds into a qual course, the gun started to seem to slow down and then I started to get misfires. The ammo had some gummy build up on them that was coming from the firing pin hole. Where the slide runs in the frame was also filled with the same gunk. The gun just stopped working. I really wanted this stuff to work so I went back and did the process again using only a small amount. Same result. I also gave some to a couple of my firearms instructors and the same thing happened to them. A couple of the guns didn't make it through 50 rounds. I also used it on my Hammerli SP20 gallery gun. Again I started to get misfires. After going through the M&P 45 problem, I knew right away what was causing the problem so I got it off the gun. I was still having problems with it so I ended up taking it to a Hammerli warranty guy in Maine. He had to completely disassemble the trigger group to get rid of it. He told me to never, ever use it on that gun again. This post is getting a little long so I won't go into detail but it also stopped a 1911 45 and a 10/22 Ruger. I finally just threw it all away. I'm glad it's working for you but, to be honest, I'm a bit skeptical. Maybe you just haven't shot with it enough to have a problem.
