Doesn't seem all that long ago that I brought up the same subject! Still, it is always worth rethinking, and that is what I have done. I'm going to stick to my original decision.
As before, I have two favorites… a 7&1/2" nickel plated .45 with premium walnut grips and a 4&3/4" nickel plated .45 with factory elephant ivory grips and a personalized serial number.
If my life depended on it, I would go with the 7&1/2" simply because it is one of the most accurate SAA's I have ever owned (and I bought my first one, a Colt, in 1967). With it you can easily shoot 2" groups at 25 years, off hand, all day long.
The 4&3/4, while not quite as accurate, due no doubt to the shorter barrel, is plenty accurate enough at 25 yards. The personalized serial number, SPD2566, reflects the initials of the police department on which I proudly served for over 25 years and my department serial number. I had a special presentation case made for it along with a self made, custom USFA label (I scanned and altered one of the USFA labels found in their boxes) indicating that it is a special order gun commemorating my time in service. Printed it out on parchment paper and attached it to the lid of the presentation case.
So… I would go with the 4&3/4. 50 years from now nobody will care about how accurate that 7&1/2" USFA was but maybe, just maybe, one of my heirs, the children of my children, will look at that 4&3/4" and think about me and where they came from. That is what I do every time I sign on here in the name of my great-grandfather Capt. John Fitzgerald.
