Saintclair:I've been using Brownells Bedding compound for the alignment holes for probably 30 or more years,& also w/ a releasing agent,it's easy to work with,don't fill the hole all the way up,only about 1/2 way then put one side @ a time on the gun,easier to hold in place & let it cure for @ least 8 hrs. when u do the other side repeat the process but this time secure the other grip panel w/the screw in place to hold it,that way when your all done u know that the screw holes will be lined up perfectly.I have about 20 extra sets of the 3rd gen SAA grips with the eagle. Whenever I buy a SAA that needs a better set of grips, I can easily go through all 20 sets trying to get a perfect fit. In the end, I usually have to revert to drilling the alignment holes out to be able to get the grips to fit the gripstrap properly. Then I have to put oil around the alignment pins (release agent) and fill the holes with black epoxy resin and place the grips on the gun in proper alignment. I then hold them in place with a rubber band and allow the epoxy to harden; remove the grips and clean up around the alignment pins.
If the epoxy seeps out and causes the grips to get stuck, that is where the Rampage comes in. Actually, the secret is to allow the epoxy to set up somewhat before putting the grips in place.
Your astute observation is well defined. Of course the correct name is Rampant Colt. I did have to go to my Rapley to help me determine the origin. My exuberance in finding this SAA just got out of hand. Any future help you can give a pore old backwoods country boy will be appreciated. Most of my collection predates the single actions with the exception of a few Bisleys. The help that you provided is so much more appreciated than those who might have felt the need to add unnecessary negative remarks. I must consider their illness of Cephalo preternatura anulosis as being a contributing factor to their bad manners.What are "Colt Rampage" grips. By any chance do you mean "rampant colt"?
