I don't know if it matters to you or not, but I believe Trijicons are made in the US and the Meprolites are made overseas somewhere. I was between the two and decided to go with the Trijicons for this reason.
i very much like the mep's and have them on a few pistols. If you are open to other suggestions though, imo truly the very best site out their is the Tru-Glo TFO's. They glow brighter than any triji or mep at night and have a very bright fiber optic for day shooting. I prefer the green rear w orange front because with all green the dots tend to blend together on me and i find i have much faster target acquisition with the orange/green
I like the idea of TruGlo's, but they are too limited in firearm selection. I have been thinking about a set for my Glock, but I carry my SP101 more often, which doesn't have any TG's available. As such, I will be ordering a Mep or Trij when they come available again at a decent price.
Good to hear about the TGs, though, I may have to get a set afterall.
I have a set of Trijicons on my XD and love em. I want to add a set to my Walther P99, but this is a daily carry gun and the Trijis for the Walther are way blockey. Im still deciding on that one, but lov ethe Trijicons on my XD
I have to agree that the Meps are brighter...when I used to own a Glock, I was able to get Meps for about 3/4 the cost of the Trijicons, and was always happy with them. My current M&P 9 has Novak Trijicons on it, my M&P 40 has the factory night sights, which I believe are also Trijicon. I don't think you could go wrong with either...
Beyond brightness, you need to consider how the sights look in daylight. I tend to like the type with a large white outline around the Trit Vial for that reason. That said, I'm not a big 3 dot fan for any sights. I preffer the XS 24/7 system for my needs.
I have a number of different types of night sights on my pistols- Trijicon, Meprolights, and MMC (when they were in business). Trijicons and Meprolights are both quality sights- the Mepros are cheaper and brighter, the Trijicons more expensive but with better customer service. I have emailed both Trijicon and Meprolight with questions about their sights- Trijicon always responds and is quite helpful, I have never had a reply from Meprolight. So I usually buy Trijicons when I can.
