We found that this gadget and a collet bushing achieved near the same level of accuracy improvement as tedious fitting. Years later when I got my hands on a Series 70 1911 Gold Cup with an exquisitely good trigger pull, I slapped in the Group Gripper, the poor man's accuracy job, and was thrilled with the results. It's probably not at good or durable as a quality accuracy job by a competent pistolsmith, but for us kitchen table gun surgeons it was was rewarding and cheap. It's still in my Gold Cup.
