If looking to use these sights with red fiber at night they do NOT glow at all. Use during the day with red fiber works great. Using with the green fiber that it comes with it works at night and during the day just a heads up if ur Gona purchase and use the red fiber sights. Spending the money to ge...

Most Helpful Negative Review Great in theory. Poor in reality.
These sights sound great but they are not as advertised. The tritium in the front sight is not strong enough to illuminate the fiber rod no matter what color you try. You end up with a normal two dot tritium glow in the rear but nothing more than a dim, fuzzy haze at the front. More of a distraction...

front tridium lamp fell out

by Orlando Agostinho, Verified Owner from NY, United States Written on May 18, 2024
I purchased these sights I month ago two range trips. Less than 200 rounds at so point front lamp fell out. Front sight was just as bright as rear sights. Waiting for OP or trijicon to let me know what I can do to try and get new front sight. Fiber is very good in day light. Must have been a reason why these were on sale. You get what you pay for a guess.
Best Used for:
  • Person defense and fun

by rachel, Verified Owner from NY, United States Written on April 17, 2024
Wasn’t sure how I was going to like the Trijicon DI night optic but once I put it on my Glock it ended up being the best sight I purchased! Does very well in the sun and the glow at night is very bright. I highly recommend for a female shooter!
Pros:
  • Bright light good quality built
Cons:
  • none I experienced
Would recommend: Yes

Trijicon DI Sights

by Night Sights for MP 9mm, from VA, United States Written on August 19, 2023
Good quality and fits perfectly in my M&P 9mm First Generation. Tritium and fiber optics are very bright when they need to be. Price from Optics Planet was very competitive. Professional installation is best. Highly recommended.

Glock 43X MOS

by Yogi HD, from CA, United States Written on September 8, 2022
Great idea, it works only with the green fiber optic sight. Red and amber will not illuminate with the tritium at night. Also with the 43X mos, the rear sight will hang out beyond the rear of the pistol. These sights allow you to co witness with the RFX-15 green dot.
Pros:
  • co witness out of the box
  • illuminated
Cons:
  • rear sight hangs beyond the pistol for the 43X MOS
  • only green fiber illuminate with tritium
Best Used for:
  • Day & Night Use
Would recommend: Yes

Clear, Bright, and Easy to Pick Up

by Echo Delta, from IL, United States Written on May 27, 2022
These are some of the best sights I've ever purchased. They are very easy to pick up, and the tritium is surprisingly bright in dim or no light environments. I find that the front sight post is large enough to easily differentiate from the rears, and aligning the dots is easier because of it. Being that they're Trijicon irons, they are built to withstand punishment too. All in all, no complaints at all from me!
Pros:
  • Warranty
  • bright
  • Durabilaty
Cons:
  • price
Best Used for:
  • home/personal defense

optics planet - disappointed

by Charles Parker, Verified Owner from OH, United States Written on May 15, 2022
I am very disappointed that this product was discontinued by Trijicon for the P320 series guns and yet you continue to sell them without providing that information to the customer.
The front sight is too long to fit in the machined area on the P320 slide. This causes the sight to be too high. Trijicon realized this and discontinued production in Jan 2022.
It’s a shame this was not disclosed and I didn’t realize this until after they were installed.
Would recommend: No
