I have a well-used but quite serviceable S&W K-22/Combat Masterpiece that I enjoy except for one factor: With every different type of ammunition, it is a bitch to eject the spent rounds. Most of the time I have to empty it by pushing the ejection rod down with an object, or against something like a wood bench. Rounds go in fine, just won't come out without a fight. Someone told me this was a chronic issue with K-22's...anybody with advice?
