There are NO stock production 1911's that will typicaly hold the x ring at fifty yards out of the box. That said, a few of the premium guns (Gold Cup, Springfield Match, Kimber, etc.) will in a few cases do so. The solution is to have your 1911 re-worked by a competent bullsey pistolsmith. Most of them gaurantee x ring accuracy out of a ransome rest with match ammo. There will be a wait for your gun though, and the cost will run between $800 and $2,000, so unless you are involved in bullseye competition, or money and time are unimportant, 5 inches at fifty yards is sufficiently accurate for most social work.
