Does anyone have an opinion on AO sights on a full size 1911? I've seen them on compact and sub-compact pistols, which have a more "up close and personal" defense application. Would the giant golf ball front sight limit any longer range 15-25 yard shooting from an accuracy perspective. I hesitate to make the change if it significantly affects accuracy. From a defense perspective, I would like to have better sight acquisition in low light conditions, beyond the Meprolight tritium sights that come as a stock accessory.
