I'm wanting to upgrade from my factory polymer sights to a set of night sights on my glock.Can't really decide which brand/company is the better choice.Is there any companies better than the other? What night sights do you prefer on your glocks?
I have Trijicon's on my G22 and only have experience with Trijicon night sights. From the research I've done, you can flip a coin between Meprolight and Trijicon because they are both great. Meprolight apparently also supplies the tritium tubes for Glock OEM, which come with a lifetime warranty if that makes any difference.
ETA: Meprolight uses an epoxy coated lens over the tritium tubes while Trijicon uses a sapphire lens, which to some people say make them seem brighter.
Don't forget about Ameriglo. They use the Trijicon inserts but can be had in the operator format. It has a narrower front blade and a wider rear notch. Also can be had without the white ring around the rear inserts.
I replaced the mepros on my Glocks with the operators. I just like a little more light on each side of the front blade instead of a solid block across.
If I remember correctly, Trijicons have a 10 yr warranty and Mepro has a 5 yr. As I understood the warranty it was from date of manufacture not sale and it was to guarantee the service life (glow) of the sight.
Trijicon seems to typically retail higher than Mepro but you can find either on sale somewhere if you use your 'Google-fu'.
Having installed both recent manufacture on Glocks at same time, the Trijicon seemed to glow brighter. Not a very scientific comparison, but was my experience.
I am a fan of novak night sights. I highly recommend getting a sight tool and front sight wrench to install the sights if you plan to do it yourself. I have installed them before using a punch and hammer but you are really running a risk of causing damage to the gun and the sights if you do so.
