Limitations and advantages of handgun sights
The real advantages I see to actually altering the front sights on handguns is for home defense. Even if you have a flashlight on or there is some lighting in your home, it’s still can have a lot of shadows and moving from room to room will give you areas where it would be good to be able to see exactly where your front sight is pointing. Hunting with a handgun or rifle usually means hunting in early morning with limited light and the same for late evenings in later afternoons. Hi visiblity sights should give you some advantages for speedy target acquisitions.
A lot of this is really going to be about conditions that you are shooting in, and it will also depend on how good your eye sight is in the first place, but traditional gun sights that are solid black can sometimes be hard to pick up in low light and even if they are being used in sunlight, they are too thin or too thick for a shooters taste. Depending on the type of shooting that you are doing sometimes the gun you have is a good format, but some changes need to be made to your rifle sights or handgun sights. Even today there are some red dot optics that I do not like because the dot is so big that it obscures the target and it makes it very difficult to shoot tight groups. Low light can make it even hard to see objects behind the the target.
