**No disrespect intended to ANY other companies, but calling it how I (and almost everyone) see it!** (Bolded Parts are the Main Topics if you are not a long winded reader) I was on a recent quest for night sights for several setups, I was dead set on Trijicons and didn't want to hear anything about any other brands, I saw it as "the best" due to the price point and I was dead set. I FIRST got a pair of: - Trijicon "Bright & Toughs" (3 white dot system) - Trijicon HDs. - Glock (OLD/Original) OEM Anyone that mentioned AmeriGlo, I ignored and thought the advantage was due to the price point... Boy... was I wrong about doubting AmeriGlo! A guy who I had been speaking with had owned them all, and kept mentioning how he had been swapping everything out for some type of AmeriGlo. After finding out Glock was setting them and outfitting *Special Edition* Gen 5s with them, I got a pair of "Bolds" (and now for several Glocks). I immediately sold my unopened HDs before even trying them out! After looking down a g23 outfitted with the BOLDS, I made my choice immediately. The others are not bad, but the OEM has the vials nearly 1/8" deep with white and silver inside to make them illuminate and give an "Orb affect* The Trijicon is good, but the front sight feels too small in size, the white paint sometimes glares/doubles (if my glasses aren't on) and I've heard that many solvents can strip the white paint from them. While others companies offer either "Option A", OR, "Option A and B" AmeriGlo* is currently working on the "Option Alphabet"! Onto the Ameriglo Bold: (Spec options first, then the Pro's and Con's below that) They have a (non sharp) .276 rear with a nice non-reflective coating, and a slightly deep set "Square Notch" opposed to the HD "U" notch. A .180 front for the most common Glock's, a .200 for the G20 and others in it's class. Here is the kicker: they even offer a .165" Front Sight for some models, and as you may know, that height matches OEM Rears and a good way for you guys with OEM plastic, or Night Sight rears to buy a better front post to optimize an OEM 3 dot system!!! They just have the edge in so many aspects; so let's get to the Pro's & Cons: - First of all, Glock has contracted them to make these for their Gen 5 Glocks (and sold sepera, as they see the huge upgrade from the old setup! - The Dots!!!! Those bright ass crisp dots... They are a crisp dots that are bright as hell in the dark with absolutely no blur! They are on another level!!! Not eye hurting bright, they are crisp/non blurry bright and due to not having white reflective paint around the tritium (or "inside" like the rears, if original OEM) they are like green crisp beams that stand at attention! Standing right at the edge of that rear and letting themselves be known! You won't have a hard time finding them! Even during the day, all 3 show dots are visible, as the rears are not muted, just more low key than traditional. The rear 2 dots are pronounced enough for those who like a 3 dot system. - The front tritium dot is larger and brighter, helping fast aqusition at night aswell, unlike most others! (Really helps seeing the front dot even when the Glock is lying at an angle, and knowing, even at night, which dot is the front just due to its size and brightness! And during the day, the orange ring makes it VERY pronounced. - The deeper "Square Notch" in the rear and Orange (or yellow) circled Tritium Vial makes finding and aligning the dot about half, or 1/3rd of the time.</b> -I love the anti-glare coating and geometry, being Ameri-glo's in general have a smooth finish that doesn't not have bare metal on the edges like Trijicon. Doesn't seem terrible, but can really cause a glare/doubling effect of the top edge in the sunlight, especially if your eyes have any issues. - Diversity and Variety!!! -Also, one thing that doesn't do unnoticed...The sheer Amount of offerings and different lines to suit your needs!</b> some that have only small differences, but fine tuned differences to find the perfect setup for your handgun!!! **CONS** I can't find any!!!!!!! The only Con was me making my original mistake and thinking non white painted rear dots are a deal breaker at all! True upgrade. In summary: - These guy have like 5 or 6 or so product lines that I hear only positivity about. Other AmeriGlo offerings for Glock and many other makes and models aswell</b>, and whichever one a consumer seems to buy first, they become set on Upgrading their Night Sights to whichever "AmeriGlo" offering they bought! -The product is a winner, even for the sceptical ones who are have the extra funds but don't like change..... GO FOR IT! While the white 3 dot system is one many are used to (myself also, comparing and choosing all at the same time), these 2 have a visible opening that works the same, and its square notch fills the gap of those who want the front upgrade but were not fans of the HD's reported "Razor sharp rear edge" when using as a carry weapon or charging it. This is the one! Just make sure to choose the generation that your Glock is when ordering them, as it will come with the proper height, as AmeriGlo has every generation/model set with the proper front height. In my final words, all I can say is, Go for it, and Good luck finding them as they are a Hit!
