So I have a 65-3 that I aquired recently and when I grab the cylinder when closed of course and move it front to back it actually moves the cylinder release button with it. if I hold the button with my thumb the cylinder barely moves at all. My other k frames do not do this at all and all I can think of its a weak spring that holds the cylinder release bar(if thats whats its called). Aside from this the gun functions fine and shoots fine. Anyone with thoughts?
