I owned 2 Boresnake cleaning products, one for 10mm/.40S&W/.41magnum, the newer Boresnake for the 9x19mm/.38/.357magnum.
They work great & I never had any problems or issues. I never shot 1000s of rounds with any revolver or pistol & most weapons I owned had CLP, chrome lined barrel or a after-market treatment like Robar's top NP3 on them.
Hoppes #9 helps,

Remington;
www.remington.com has a new cleaning/gun care product called SQUEGE or SQUEEGE; check the website or
www.youtube.com . They claim it works on firearm barrels from .22LR to 12ga shotguns & cleans in "one pass".
Mpro7 now has a special Boresnake too, R&D with Hoppes but I'm not sure if the Mpro7 Boresnake is a Viper or the old brand.
