Groo here
The Ti cylinder should not be touch with any hard brush or not approved cleaner!!!!!!!!!!!!!!!!
If you intend to shoot it alot, send to S&W and have a SS cylinder fitted.
This will take the cleaning and add some weight to make it nicer to shoot.
Shoot the SS ,,carry the TI...
I have one [a 2in 327] and only use some oil and a rag.
