TRUGLOTFO Tritium & Fiber-Optic Handgun Sight | Snag-Resistant Front & Rear Bright Night Sights, Compatible with Glock Handguns

Very Happy with this purchase! First off let me point out that the earlier reviews of these sights complain of the front screw being to long or otherwise for the gen 4 Glocks. Mine came with the proper screws for both the Gen3 and Gen4 use. The front sight fits slightly loose in the slide slot just as it should so you can make adjustments for proper alignment. I set mine straight with a small straight edge/ruler laying up against it and down the length of the slide BEFORE I put the rear sight on and it was very easy to line it up properly. The stock front sight screw was set further forward in the slide making use of a socket on the screw to remove it impossible because there was zero room between the front edges of the screw/bolt and the front of the slide. However, since the stock front sight is made of plastic the bolt is not really all that tight and I used a small set of needle nosed pliers to get mine loose with little trouble. The Truglo front sight has it's mounting bolt set back further towards the rear of the slide slot making use of a socket to tighten the bolt with my standard Craftsman 3/16" socket doable. Coat the cleaned bottom of the front sight with Loctite making sure you do not get any in the bolt hole and set the sight onto the slide. The bolt only needs the very smallest little dab of Loctite on the tip of the screw before inserting it. To much and it will never come out without breaking it. Snug the bolt slightly then align the sight then finish tightening the bolt. DO NOT over tighten! The Loctite on the sight will do a fine job of holding everything in place, the screw just needs to keep everything in place while the Loctite cures and moderate screw tension will keep the sight in place for years.My Factory rear sight was pretty easy to remove with a brass punch/hammer and the slide mounted in a bench vise. USE SOFT JAWS or wood or several layers of hard cardboard taped to the vise jaws in your vise if the jaws are serrated or you will get marks on the sides of you slide while tapping the new rear sight in. Check for fit. If the rear sight goes in almost half way with moderate tapping with a punch you should be able to install the rear sight. If it stops way before getting near halfway in STOP and remove the sight for fitting. Using a small triangle file gently take a few swipes on the sight dovetail on each side and recheck the fit. Repeat until the sight fit is proper. On final installation of the rear sight put a small drop of Loctite it the dovetail on the slide. Using a punch carefully tap the sight into place centering it as best as you can. I used a depth micrometer to center mine but you could also use a dial or digital caliper to check from each side of the slide and get the sight centered as best as you can. The set screw only needs the smallest amount of Loctite on it to hold it and for Heavens sake DO NOT over tighten it! The included Allen wrench with my kit was a slightly sloppy fit in the set screw. This could make the wrench and or set screw easy to damage if you over tighten it making it impossible to get apart later if needed. Remember, the fit in the dovetail is what is supposed to keep the sight in place, not necessarily the tension on the set screw. It is best to let the gun sit for several before hours shooting to let the Loctite cure properly.In the end, I am very happy with this set of sights on my Glock 26! After centering the rear sight on my slide it needed no further adjustments for my shooting. As a side note I left my slide on my bedroom night stand the day I installed the sights so the Loctite could cure someplace warm instead of my cold garage. I was pleasantly surprised to see the Tritium vials glowing in the dark when I turned in to bed that night! Not super bright (which is really not good) but plenty bright enough for night time social use! Thanks for taking the time to read through my lengthy post and I hope this helps someone with their decision to purchase or the installation of these sights! Enjoy...

I bought this TRUGLO TFO Sight Set for my Gen 3 Glock 30 .45acp. The factory sights were just 2 White Dot rear, and White Dot front sights, that are near impossible to see in low light or darkness. Since this G30 is my daily Concealed Carry weapon, I want to actually be able to see the gun and sights if I need to use it in night situations.The factory front sight was pretty easy to remove, but the rear sight required a sight push tool to remove it. I bought a tool from Sylvan arms, here at Amazon, and removal was amazingly simple.When I removed the front sight, I added a small drop of oil to keep the area under the screw free from corrosion. Then just lined up the sight with the hole and tapped it with a small wrench to seat it in place. Getting the new (included) screw in, was difficult because of the size. It is a tiny screw, so just used a pair of needle nose pliers and a lighted magnifier to line it up and get it started in the threads. I used my tool to tighten the front sight, and it fits perfectly. TRUGLO says not to use a sight push tool to install the rear sight but how else can you install it. It is extremely tight in the dovetail. I used the Sylvan sight pusher and just took my time, while making sure that I didn't turn the pusher too fast. I will say, that if you take your time and make sure that your sight pusher lines up at the base of the sight in the dovetail, that you will have no issues. I guess that TRUGLO wants to make sure that you don't crack the Fiber Optic section of the sight. Again, just make sure that your pusher contacts the sight at the lowest point in the dovetail. You will be just fine.The Fiber Optic is very bright and the Tritium glows brightly, even in total darkness. This sight set is AMAZING!!It is a little on the expensive side, but I wanted both FO and Tritium in my sights.I got the set with the yellow rear and green front. I wanted to be able to distinguish both the front and rear sight easily. That's why I didn't want the all green set.If you purchase this sight set, I think that you will be Totally Satisfied, as I am, with the quality and brightness.Tomorrow, I go to the shooting range to sight in the pistol and I expect to enjoy shooting with the new sights and to have no issues.
