    I knew I hadn't taken apart a S&W revolver in some time but this was something new to me.

    [​IMG][/IMG]

    Underneath the thumbpiece part on the inside there is a small silver doohickey that slides in a verticle track. It's not held in except by the rest of the parts that assemble over it. Whatinheck is it for?

    Just wondering?

    It does not appear in the Kuhnhausen manual anywhere; it's not the lock is it?

    You will find that small part on the .44 Magnum, it prevents the cylinder from flopping open under heavy recoil. The hand stud rides in the grove and when you pull the trigger, it locks the bolt into place so it cannot move.

    Yes, that is the renowned Model 29 44 Magnum. Sorry I did not mention it. I've had the earlier version but this is after they got rid of the pin and recess. The gun is off being engraved and I forget if it is a 29-4 or -5. That must be part of the endurance package that was included after 29-3? It's heck when your memory erodes... what were we talking about? :eek: :neener:

    I can visualize how it works, now that you mention it, Kurac. The part rides up with the hand and blocks the thumbpiece from moving back.

    It's called the bolt block, and yes it's part of the endurance package.
