Hands down best sights you can buy for your handgun in my opinion. I went with orange front sight very quick target acquisition day and night, tritium glows perfectly at night love the U shape verse Square back sight as well. Only reason I'm not giving 5 stars is as a few others have mentioned the trijicon printing on the sides of the sights are worn and can hardly read or see the trijicon print makes them look old and for the money should have better quality control. That being said I would still highly recommend them. If trijicon sends me a new set with good clear print I'll update my review.

I have these on my Glock 19, Glock 42, Dan Wesson Valor (rear sight is different on this gun) & my Sig Sauer M11-A1. These are without a shadow of a doubt my favorite sights. I am a NRA certified advanced pistol instructor and I shoot a lot and a lot of guns with a lot of different sights so I am saying this from a wide range of experience.

Arrived on time, in good condition, functions as described. Superb night qualities, exactly the right brightness and color for fast acquisition under low light. The coloring is also excellent for daylight use. Extremely well constructed, surprisingly rugged for such delicate components. Rear sight is solid enough for one-hand slide racking using belt or boot. Very satisfied.

This is my 2nd purchase of this product. I have them on my M&P Shield and my Glock 19 Gen 4. I always purchase the yellow because it stands out more to me. Some say the orange stands out more to them. I think it really depends on your vision and what colors you see better. I would highly recommend this product.

Second set of Trijicon HD's that ive purchased, have the orange on a VP9 and bought the yellow set for my glock 43. Like most folks I couldn't decide between the colors (yellow vs orange) so I thought I'd try them both, I'm still not certain of a clear winner but the orange does seem to be a little easier for me to pickup outside in bright conditions... I debated on trying the Ameriglo I-DOT pros as they share a similar front with a single tritium insert in the rear and are substantially cheaper but after being completely satisfied with the HD's on my VP9 I didn't want to gamble.

I've used standard trijicon night sights, heinie straight eights, novaks, HK photoluminescent and several other aftermarket and factory sights and these are by far my favorite setup to date. If I had one slight gripe about them it would be that I wish the rear trijicon inserts were yellow instead of green to help with differentiating them faster in low/no light conditions. I found that a dab on each of the rear inserts with a red highlighter works for me though, it still allows the rear dots to be visible to improve accuracy in the daytime and dims them just enough to help the front sight be more pronounced than the rear in low light situations.

I'll be adding these to some other guns in the future and would definitely recommend them.
