Thanx, that makes sense. :?
I have a knurled head base pin screw that angles up into the base pin grooves to keep the base pin in place. Since it has a knurled head... it must be meant to be finger tight... but I'll wager my next paycheck it will work loose dang quick. Keep in mind my base pin is fine... it's the screw securing it that I'm worried about.

"I have lost base pins from Colts, Rugers and Great Westerns. In addition, single-actions are often somewhat loose if the cylinder pin is undersize. Belt Mountain addresses these difficulties by offering replacement base pins in several types, all of which are .002" oversize for a tight fit of cylinder-to-frame.
Both blued and stainless versions are offered with an Allen screw in the head of the pin that can be tightened against the bottom of the barrel to prevent movement under recoil. The latter comes with a standard size head or an easier-to-remove knurled head."
