Until some time ago when I started reading all these conversations on short arbors I never knew there was such a problem with Colt replicas. I had always shot a Remington nma. Now I understand the problems with the Ubertis and the short arbors. All of my Colts were originals and I never shot them, but within the last year to year and half I have bought 2 Dragoons, an 1849 Pocket Model, and 1862 Police, all new by Uberti. I have not fired them yet. I don't have a shop, the tools and equipment some of the members here mention, and am not mechanically inclined. I don't even have a vise. When I finally order a Kibler kit I will probably assemble it sitting on a bench on my front porch with it across my lap. That said I put a washer in the arbor well of each of the Dragoons as a spacer. I may not shoot them alot, but when I load them I will probably be using something close to a service load. I don't plan on using them in matches. Other than the weight I can't get used to sighting through that notch in the hammer, so the Remington will continue to be my match revolver. On the other hand the pocket model and the police are small frames and take light loads. It seems I read somewhere on here that the short arbor not being corrected on those types may not be nearly as damaging to the firearm as on the larger models. Should I be able to get away with firing those without worrying about the arbor and not damage the firearm? On all of these mentioned the primary purpose of my firing them will be from an historical perspective, to get the feel occasionally of what is was like in the old days when that was what people had to rely on. Thanks to 45D, Mr. De land, and all others who have been posting on this subject. I have learned alot so far from all of you, and I know I still have alot to learn.
