Only 2 things need to happen in order to make good accurate hits on target every time.. Pulling the trigger without any muzzle movement. Simple! However it’s much easier said than done, this why we need to invest in consistent, proper training on the range to get it right.
Handguns are much smaller with a much shorter barrel length, which makes it much harder to manage accurately verses shooting a rifle. Everything is magnified from inconsistencies in trigger manipulation to any discrepancies in the sight picture and any slight movement as you pull on the trigger can cause you to miss the target you intend to shoot.
