I have used Breakfree CLP, Hoppes #9 and M7Pro on miy 442 over the years and it looks fineHas anyone used Breakthrough to clean a black J-frame? I've read about that particular solvent causing issues with some black finishes (Dan Wessons, if I recall correctly). Just want to make sure I don't cause any issues before I clean my M&P 340.
I have not heard of or tried Breakthrough. At first I thought you meant Break Free CLP.
I would err on the side of caution if you do not hear that Breakthrough is okay to use and not use it for that particular gun.
Is this the product you’re asking about?

That’s the one! It works well on my other firearms. I used to use Hoppe’s Elite, but the last time I went to buy it, I couldn’t find it anywhere.
