Is this a “new” gun or just new to you? Why do you think it needs action work? Have you dry fired enough to smooth it in? Are you planning on a lot of DA shooting? Remember that a rimfire needs a heavier action to be reliable. I have done a lot of action work on guns that owners never shoot double action… Note: We will assume you will be using snap caps when dry firing due to potential cylinder / firing pin damage. It is difficult to include every caveat in a short reply.
