I just put money down on a New Service today! Have to wait till Monday to pick it up. It is in .45 Colt. It has plastic grips with Colt molded in it and has the landyard loop. It is reblued to a highly polished dark blue. I would prefer the original finish but it is not as important to me as the lockup and bore condition. This gun is excellent on both counts. Can't wait to put my handloads of 5.6 grains of Red Dot behind a 250 grain lead rnfp and see what the gun can do. The current .45 Colt bullets I use are sized .452. Will I have to track down .454 bullets? Also, the serial number is 343XXX. Anybody have the born on date?
