wise choice with the wiegand base. get their rings too they are SUPERIOR to any others.
when i first got my 460 the wever bases wern't available in steel so i put on an aluminum BIG MISTAKE - DON'T DO IT. the recoil lug in back pened and all the screws sheared off. scope hit forehead then ground.
weigand mount was removed to return revolver to s&w to have custom shop do a trigger job on it. when re-installed it was dead on at 200 yards, litterally not an inch off.
best mount on any gun i own
