The Belt Mountain Pin Will Work!

Adam,

I did have that problem with old factory cylinder pin on my Ruger Blackhawk .45 Colt (1976 Vintage). The problem was not that the Ruger pin is bad. The problem is wear! Ruger, Colt and any other single action six-gun can have the same problem.

The older Colt's negated this problem with the sleeves on the pins.

Belt Mountain and Bowen both have oversized pins for most if not all of the single actions. Both pins have locking screws and come in several style of heads.

These will cure the cylinder jump problem that you are talking about.

The problem that GoodOlBoy is talking about with the transfer bars breaking was due to the placement of the cylinder pin while locked down.

The oversize pin refers to the diameter of the pin not the length. The slightly larger diameter helps with wobble and end shake of the cylinder. This makes the revolver more reliable and accurate.

When I fitted the Belt Mountain pin to my Blackhawk (i.e. slid it into place) the spring loaded plunger in the end of the pin to keep the transfer bar pushed back away from the firing pin kept the pin from seating down against the frame. If you look at the same installation with the factory pin it does the same thing. In other words, its designed that way.

My problem was that due to esthetics (just my need for what I though looked right) I seated the pin flush against the frame and then tightened the locking screw down to hold the pin in place. The pressure that the spring loaded plunger put on the transfer bar with all of the pressure against it created a stress problem and broke the transfer bar after a few/many times of dry-firing. It never happen'd while firing live rounds!

The cure from that point on was to let the new pin seat itself and not push it flush against the frame before tighting down the locking screw. After doing it this way, all was right with the world.

NO STONING OR FILING WAS NEEDED OR SHOULD BE DONE ON THE CYLINDER PIN!

What GoodOlBoy was thinking about was on another revolver not on the Blackhawk.

If you or anyone else have any questions just let me know.
