Man, I never knew that there were so many selections of sights for the Glock.
I have a new Gen4 G17 and want to add some new sights to it. I know you pick them on the basis of how you will use the handgun. I plan on using it for home defense and target shooting.
I'm leaning towards the XS STANDARD or the XS BIG DOT sights.
I've mounted a set of XS 24/7 Big-Dots on the Glock 19 that is in my carry rotation. During the daytime, the sights are easy to pick up and align. Dot the "i", put that big golf-ball front sight on top of the vertical line in the rear sight valley and you're good to go. Very easy to maintain a front sight focus for very precise shot placement. The sights also accommodate a two-eye open sight alignment. I find that the XS-Big Dots are great for fast combat accurate hits on target. After practice, I can achieve more precise slow fire shot placement. For me, XS 24/7 Big Dot sights are the most useful practical combat
self defense sights. The caveat is that they are not bullseye sights. Three-dot notch & post sight will enable the marksman to more easily achieve slow-fire, small hole in paper groupings that look great in pictures posted on internet forums.
For those that are unable to practice often, any sighting system won't provide the best results.
I've also been trying out the new Mako FT-Bullseye.
It's unique. It employs fiber optic rods + tritium vials + a lens. I assume my normal stance holding my firearm out, and I see a green dot within a green ring. Dot on target, both eyes open, and that's where shots go. It's similar to shooting with a pistol mounted, battery powered optic. The FT Bullseye sight isn't as fast as a pistol mounted optic, but it also doesn't require slide milling + a $450 optic. They also don't require any special tools to install.
The unique aspect is that there is no need for a front sight at all.
I also like the fact that Dawson sights come with the sight install tools.
Decisions, decisions!
The only tool you really need for a Glock is a front sight hex screw tool. XS provides one with their sights.
I purchased an inexpensive Glock pistol sight pusher for $30.
They're a bit more fiddly to set up than a $130 MGW sight pusher, but it works. I've used them to install several Glock rear sights over the past two years. I definitely got my money's worth. Truthfully if I had known I'd be installing as many Glock rear sights on my own and friend's pistols, I'd have purchased the MGW sight pusher.
Even though the Glock sight pusher is convenient, it's a single product tool. When I install sights on other pistols, I still use a non-marring punch and a non-marring hammer.
