TRUGLO Fiber-Optic Handgun Night Sight | Compact Durable Snag-Resistant High-Visibility Red Front & Green Rear Sight for Handguns

The sights are really nice and bright. Definitely an improvement over factory. I would recommend these for any kind of daytime use. I will say that they are completely useless in darkness, but I didn't want to deal with the temporary (and expensive) nature of tritium. These will last forever, provided that they don't get damaged.Installation with a NC Star sight pusher was as easy as anything else. Mine are not perfectly adjusted, that's something I'll have to work on when I have more range time, but I tested 50 rounds and the grouping was solid (high and left when aiming center. That's way good enough for a quick install without a boresighter or more meticulous testing. I would recommend these to anybody in need of aftermarket sights. Five star!

These are nice, bright steel sights and Amazon has the best price I could find . I only wish they had side-cutouts to let in more light when the light source is not overhead. In usual conditions, these are VERY bright.I had already replaced the stock sights on a Glock 43 with these and decided to buy the larger version for my full sized Glocks.I caution that you will need a Glock front sight tool and a rear sight pusher to install these. The VISM rear sight pusher and a magnetic front sight tool, available on Amazon.com, will likely cost as much or less than a gunsmith and you can use them over and over.You will also need some blue or purple LocTite.Disassemble a firearm after clearing it, remove the barrel and the recoil spring. Using the front sight tool remove flat hex screw holding the old front sight in place. With the slide upside down and suspended it over roll of masking tape use a small punch and gently tap out the old front sight.Using the small hex-key supplied in the kit, clean out any old Loctite from the oval cut out in the front slide. Place the new front sight into the oval cutout. If necessary, gently tap it firmly into place... ( I used the back of a small wooden screwdriver.) in my experience, this front sight fits very snugly and is perfectly parallel, without any wiggle.Place the hex nut into the magnetic driver. Do not apply Loctite on it at this time. Drive screw home to see if it fits snugly. Is it does remove the screw and apply Loctite to the threads and reinsert it. If it is too long, use the shorter Gen 4 screw that is supplied in the kit.Wipe off any excess Loctite with a dry Q-tip. Next go over the site with a Q-tip soaked in bore solvent. Your front sight is now installed.For the rear sight, please refer to the numerous YouTube videos on the use of your own particular rear sight pusher.Do not forget to completely remove the Allen screw from the rear sight before installation. Once the rear sight is exactly where you want it, apply Loctite to the Allen screw and insert it using the hex key into its hole. Using a Q-tip wipe up any excess LocTite. Ask before use a dry Q-tip first and then one soaked a little bore solvent second.

bought for Sig P238. Easy to put in as long as you take you time and have good punches. Be really careful with the little spring under the rear sight. I did as others said and put the slide in a plastic bag so when it sprung out I didn't lose it. Unfortunately when I install the new back sight I bunged up the tiny spring.Be careful or take it to a gunsmith. If you do mess the spring up they are near impossible to get and are expensive. I was able to find some look alikes on Amazon cheap though that work.

I bought this sight set for my Glock 34 G4 pistol. They were relatively easy to install, but the rear site did require a couple passes with a small file to get it in to the dovetail. I used a sight pusher tool to install the rear sight and it worked fine. The rear sight is not as wide as the factory part, so I centered it left to right in the dovetail and then adjusted from there after putting a few rounds though it to sight it in. With the rear sight centered in the slide, it was very close to dead on, only required a small adjustment to make it shoot perfect.There is a set screw on the rear site to lock in in position when you have it adjusted, and the allen wrench is included, however the one that came with mine was useless. It was either made undersized or of really crappy steel and it rounded off when I tried to tighten the set screw. Fortunately I had the proper size allen wrench, but it is something t be aware of.The front sight is a little tricky to install, but the instructions provide the important detail. You need to hold the slide upside down and set the screw into the sight hole then line up the sight underneath. Be sure to put some thread lock on both the front site screw and the set screw for the rear site. On the Glock 34, the front sight does hang over the opening on the top of the slide, but this should not cause any issues.Overall the sight is bright and easy to use, but it is not as bright as other fiber optic units that I have used. Outside in sunlight the sight only looks a little brighter than painted sights, but in the shade it looks very bright. Indoors it seems somewhat dim, but still very usable. The light pipes on this set are larger than others I have used, and I would actually prefer that they were a bit smaller. The big "dots" make them fast to acquire, but they feel a little vague and less precise than units with a smaller dot. The fiber rods seem to be well protected so they should stand up well to rough use.
