I Think The Colt Pistol Part Of This Thread
... Has pretty much run its length (but don't count on it!). You must understand that when we antique fanatics find something we generally run it to ground, so to speak.
Now to your ROA.
I have always admired Ruger guns. IMO, they are very well built for the most part. I have no knowledge of the ROA as a hands-on pistol, but I have previously owned a Ruger SBH .44 Mag 3 -screw (now my son's pistol), a Ruger Mark II Target 7-1/2" .22 (a pain to reassemble until you are well versed: I shot a Ruger MKII bull barrel stainless years ago, and I agree with the shorter barrel insofar as balance), a Ruger SBH New Model that I sold soon after purchasing because it was not nearly the gun as the 3-screw, and a Ruger SP101 3-1/16" in .38 SPl. I have replaced the springs (with Wolff) on the SP101 and it now has such a slick action as to not be believed. But, I digress.
That said, tell us much more about your ROA .50 cal conversion. We may have given you a short history of your Colt Pocket Pistol, but enlighten us as to your new-found delight. I like "fantasy" Colt revolvers and this ROA of yours is probably much more of a fantasy gun than even the original ROA, with all of Bill's improvements upon the original mid-19th century Colts and Remingtons.
