Handguns can have dot, telescopic or open sights however, the best sight for the handgun is the open sight. You can find out more on the types of guns and the type of sight that works best for each here https://studentshare.org/miscellaneous/653256-gun-safety. This type of is made of both notched rear sight and a post front sight and is the best choice for a handgun because:
- Open sights are not only simple- Unlike the telescopic and dot sights, open sights do not require a fragile telescope to magnify the target or optic fibers that project glowing dots. They also allow the shooter to see the target easily.
- Affordable- since they do not use telescopes or optic fibers, they cost much less than the telescopic and dot sights. They can also be fixed or adjustable, giving the shooter the advantage of both for the same price.
- The procedure for aiming using the open sight on a handgun is quite standard; the shooter has to center the top of the post with the notch at the rear sight and line this up on the intended target.
