What is the preferred method to clean a 340PD revolver (titanium cylinder and scandium frame)?
There is not much detail on the manual at the Website. Have a email to S&W but no response.

I don't clean mine any different than any other revolver. Your standard solvent of choice.

i put a titanium cylinder on my 642-1, and shoot it some nearly every trip to the range, since it's my usual carry gun. i also clean my guns every time I shoot them, so it's had many cleanings. I just use Hoppes No 9, since I've been using it for 50 years. At first I used a brass brush for the cylinder chambers and bore, then purchased and switched to a nylon brush, and also a flat nylon brush for the front of the cylinder and forcing cone. No damage yet to the cylinder that I can detect, but I'm interested in seeing other replies.

What was the weight savings going from the steel to titanium?

14.2 ounces steel, 12.0 ounces titanium. That's with Altamont wood boot grips.

Was it worth it? I don't know. No regrets, but probably wouldn't do it again. You can tell the difference, though.

So sounds like the frame weight difference between aluminum and scandium is minimal. Guess maybe the real difference is strength.

I have always used Hoppe's #9 and/or mineral spirits for cleaning my S&Ws but because of the cautions about the coating on the Titanium-alloy cylinder of the 340, I bought some CLP, which is what S&W recommended at that time. I use it with nylon brushes. I have to say I am not in awe of the stuff, but I guess it is OK. The barrel is stainless steel and can be cleaned normally.

Suppose to not use cleaners with ammonia and never scrub the Ti cylinder face with anything but a toothbrush if at all. Many threads on the topic if you use the search feature.

There are tens of method out there on how to clean a revolver effectively. Here is a more informative methods by NRA NRA Family | How to Clean Your Gun

Not very informative...does not address titanium. A 340PD is not your everyday revolver.

I cant get these burn marks off, but they are common and dont effect function.

Leave the burn marks: they show the gun has been fired, and as you say, do not impede functioning. As to cleaning, I have read caution must be used cleaning the Ti cylinder. The source I read suggested Hoppe's Elite which I use on these Ti cylinder revolvers.
I also refrain from brushing the cylinder surfaces.
