I set out to build the Ultimate big bore fighting revolver 30 years ago . I had a decent US postal service 1917 Colt New Service .45 acp and sent it to Cylinder and slide after using it for about five years and "only if" thinking because it ran so nice on steel plates and the bowling pin rage. Cylinder & Slide gave it a complete rebuild and blueprinting . They have a 10 pound DA and a 2.5 pound SA and the pull thru is amazing ly smooth, like a big Python. They replaced the barrel with a 4" Douglas Air gauged heavy barrel with a little faster than normal twist (1-14" ) for .45 acp at my request. They talked me into a custom shroud for the ejector rod and crane to lock into ball detents. They fabricated the gold flat topped bead front sight and welded and set the rear sight notch to put 230 grain .45 acp mill spec ball to be dead on at 25 yards . They then sent the pistol to Colt's custom shop engraver who did minimal Bank Note engraving and polished gun for a Royal Blue finish . Then Roy Fish Paw got the gun before I got it back and he fitted to my hand drawing 4xxx exhibition French walnut grips that fit seemlessly and points like my thoughts. I fitted up this French case and it is a wonderful joy to shoot the moon with my cast 250 grain Keith hollow points at 900 fps +_ into an inch at 25 yards sand bagged . It is retired now allways faith ful. I have another (few) .45 New Service Colts and one is a super smooth old reblued 1917 that Armand Swenson put some S&W adjustable sights on and tuned the action . That is not quite as accurate as the C&S Ultimate Pin revolver , but I carry it around in a full flap Lawrence holster banging around remote Oregon
