Just one, which also happens to be my very first-ever handgun...a 6.5 inch barrel Ruger Single Six. As an aside, it came from the factory blued, but over 10 years ago, I sent if off to Mahovsky's, and they applied their SS Chromium M finish to it. So, now it looks like it's got a matte stainless finish, which looks great, no visible wear anywhere, and rust simply does not not happen.
