I just feel carbon steel has a more fluidly smooth action over the stainless pistols I own like my P220 Elite which is a great pistol for sure and yes , I'm using the recommended lube ! I know they make the P210 in carbon steel but would like to see carbon steel models at about half that price !
Other makes as well , like S&W bringing back the model 952 in carbon steel as an example ! I know stainless is nice for being more rust resistant in certain conditions but a few carbon steel models I'm sure would be popular ! I wouldn't hesitate to grab a Sig P220 in full carbon steel if it ever was produced !
