MEPRO Tru-Dot R4E tritium Night Sights with Five Sight Alignment Elements Compatible with H&K Glow on Sight self Illuminated Meprolight Fixed Metal Sight

They are a bit dimmer than I expected, but they definitely fit my holster just fine. I have the older VP9 model and a mission first iwb/owb holster. I like the sight picture on this.

First of all, I ordered these in 2020 and the date stamp on these sights indicates they were manufactured in 2016. Your mileage may vary but I was not happy receiving night sights that were over 3 years old. Second and most importantly, these sight are almost suppressor height and the rear sight has a pronounced shelf in the front which is quite different than the low profile stock sights. On it's own, this is a nice feature as it would allow for one-handed racking of the slide against a hard object. The sight picture is also quite nice. The problem is between the rear sight shelf and both the front and rear sight being higher than stock, holsters may or may not fit. Of the 3 hostlers I own, 1 fit fine, 1 required some coercion to fit, and one would not fit at all. I find this to be a big enough issue that I would avoid these sights unless you do not plan to use a holster or already know your holster will fit.
