I have stock sights on my Glock 19, and I’d like to upgrade them. It is my nightstand gun and is equipped with a Lightguard (though I have a flashlight next to it as well). Not sure how the sights will interact with the light.

Looking for information/opinion on night sights for this setup AND for my carry gun once I get one. XS Big Dots seem to be popular on the forum, but any input is welcome.

Also: what level of skill/experience is required to install them? Will I be able to or should I just get them done?

Thanks all!
