I've been using it on all of my handguns and long guns for about a year and I love it. The more I use it, the more I love it. Subsequent cleanings are incrementally easier and better. I also use a tad for lubrication after cleaning is done. I've also noticed it repels lint and dust, especially on my 442 when pocket carried. That is an important feature to me. If you try it, I assure you that you will really like it. Especially on your second, third, fourth, etc. cleanings. You'll notice how much easier it gets.
My stainless steel SP101 used to be VERY difficult to remove the black from around the forcing cone and the front of the cylinder. Not difficult any more.
I've also cut my cleaning time in half, and I don't get crap from the wife about the smell. It doesnt' irritate skin or hurt any surfaces. By far my favorite product.
