I’m practicing with my new Glock 30. I keep shooting low. While it’s easy enough to compensate, and Glocks have a different point of aim than Springfields, I blame the Glock’s sights. I reckon they’re a lot harder to line-up on the vertical plane than traditional three dots. So I’m swapping them out for greater accuracy. Meanwhile, I’m having an XS Big Dot mounted on an a customized Ruger SP101 revolver. The dot is ace for CQB. So what sights do you use? Are they original equipment? How important are night sights?
