As my eyes get less capable, my iron sights get harder to use quickly...So I went to peeps, which helped - For now. I know I will eventually need to scope most, if not all my guns, but I will use 1x scopes on guns like my Remington 141 pump, (and my slug gun) because I only need the crosshair, and it's my 100 yard (and usually under) woods rifle, that doesn't need magnification. Now a reflex sight may or may not be more convienient on a handgun, where weight is a consideration (I have one, but I'm still not sure how much I do or don't think of it), but I much prefer the scope over reflex or red dot sights for long guns.
