Bought the Mepro (ML 11545) night sight from Optics planet for use on a HK P30, together with Trijicon HD SP101Y for use on a XDM. It was a deliberate attempt to compare the two well known sights at the same time, albeit on different guns.
Had some discussions about the two sights through the OpticsPlanets QA Dept before purchase. Very prompt response and customer focus from the QA lady as well as the product specialist. A pleasure to deal with, and a credit to Opticsplanet staff.
Rather than roughing it out with a punch to install it myself, I sent it to a proper armorer for installation with a press and zero the sights with a laser. The Mepro sight was very easy to install, and got the original HK sights back, intact. (they are good sights by their own right). An Armorer with proper equipment is well worth it, since Tritium tubes are involved.
The Mepro sights were brighter than Trijicon HD in no lights conditions, but both are equal in low light conditions, at least to my eyes.
In daylight conditions, they are comparable. Mepro has surrounded all 3 tritium tubes with high visibility paint, where else Trijicon HD has a large circle of hi visibility paint around only the front sight tube.
I prefer all 3 dots to be equally visible, but I can see that some people might prefer the front dot to be more visible than the back ones.
For me, the very visible front dot mutes the appearance of the two back dots on Trijicon HD.
Considering the price difference between the two, Mepro is a better buy in my view.
I tried out the hook feature at the front of the rear sight on Mepro for one-handed slide actuation. It is doable, but it is hard on your pants & belts. And since it is a home use gun, I cant say this is a very useful feature for me.
Both are good sights, so we are comparing the last 10% difference. The price difference is rather large of course.
I probably will stick with Mepro for my future night sights needs.
Pros: Excellent visibility & functionality
Cons: no major issues
