Excellent advice/comments right here...!
This question reminds me of when I bought a Les Baer 1911 a few years ago, and paid extra for the "1 1/2" Guarantee." I'm sure the gun will shoot 1 1/2" groups at 25 yards, but I'm also sure that I can't!

. At least not off hand... I just bought it with that option because I wanted to know, in my mind, I had the most accurate gun available. Maybe it helps the gun's overall value, too?
I've got a M41 from the early Seventies, very nice, reliable, and accurate gun. For whatever reason, I tend to shoot my .22 Smith and Colt revolvers more...
