The first thing you need to do when learning to hit your target is paying attention to your front sight.   It’s funny how, after time, its very easy to adapt to different scopes, iron sights ect quickly when you’ve had some range time.   Someone with experience just moves their head around until they find the sight picture while an inexperienced person might have trouble even finding a reticle.  Eye relief can vary from optic to optic and there are big differences between something like the Trijicon TA11H-G and the Ta31F-G.   There are plenty of reasons to move away from just having black on black front and rear sights but you don’t have to put something that also announces a bright neon color on your firearm.   I’ll never forget the time I was changing a target at 500yds, during a cease fire, and could see the glimmer of various objective lenses and neon strands across the tables.    There are reasons people wrap rags around their scopes to limit the fiber optic exposure and there are reasons for kill flashes on objective lenses.

Even though handguns aren’t usually decked out with too many optics,  I’ve seen some very hi-visibility sights that are too visible on the other side of the barrel.   For the same reasons flashlights can be a target indicator, so can your sighting system on a rifle or a handgun.   I have several of the older Trijicon Night Sights on various pistols and once they get to about 10yrs, I have to replace them.   I lean heavily toward the Trijicon High Definition Night Sights since they have very good application in low light as well as extreme clarity in day light.   They are available for Glock Firearm, Sig Handguns and Springfield XD.   Definitely consider looking them over because they are one of our hottest selling replacement sights.
