## Description

desertcart.com: MEPRO Tru-Dot Adjustable Night tritium Sights Compatible with S&W K L N REV Green tritium dots Glow on Sight self Illuminated Meprolight Fixed Metal Sights : Sports & Outdoors

Review: Solid night sights - I bought these for my Smith and Wesson 686 Plus revolver. The rear sight is much more robust than the factory rear sight blade, which is pretty thin. The sights are really bright in a dark room and easy to pick up with your eyes. For night sights you can't beat this price and they only add to the functionality of your firearm. I can't speak to ease of installation because I had a gun smith do it. I have not previously owned any firearms with Meprolight night sights, but I know several other people who have used Meprolight. Until now, all my night sights have been Trijicon or Glock night sights, but I find these Meprolight sights to be as good as any other I've used. I'd always recommend night sights on your firearms and these can't be beat for price and quality.
Review: Improved sight acquisition in dim light, but will require some hand fitting - I have a S&W Model 66-8 Combat Magnum. I ordered these tritium night sights with a little trepidation, having read some not so great reviews about fitment issues. I am happy to report that I had no issues with the rear sight spring and plunger fitting into the windage adjustment screw. I did have to file down the base of the rear tritium sight because it was fitting a little too snugly to allow smooth windage adjustment. Other than that, the rear sight was a very simple swap affair. The front sight is made to be slightly oversized so that it will fit tight into the red insert dovetail. I had to knock out the red insert first with a brass punch, then use a file to remove a small amount of metal from the tritium insert. I only removed just enough to allow one side of the insert to get started into the dovetail slot. Once started, I used a plastic punch and hammer to drive the insert the rest of the way into the dovetail till it was flush on both sides. It took a bit of force and mangled the tip of my punch, but I am confident the insert will not be going anywhere, even with the hardest of recoiling magnum loads. The tritium dots are easy to see with dark-adjusted vision and are not all that impressive under daylight or typical ambient indoor lighting. They are not glow-in-the-dark and won’t glow with anywhere near the same intensity, but they will stay glowing at a steady state for over a decade and not require any prior charging with light. At the range, I found the sight dots easy to acquire and shoot with. The front insert is really no taller than the top of the front blade and so, should not change that aiming reference. The rear insert is taller than the OE blade and so, left at the same height, I was hitting about 3” high at 10yds. Thankfully, I had enough elevation adjustment to bring things back down to point of aim, but just barely so. Overall, I think these sights are a worthy investment if one is willing to put in some hand-fitting effort and is looking for something that will perform better in low light. It took me about an hour to install things with all the hand fitting I had to do. I am pleased with how things turned out for me.

### ⭐⭐⭐⭐ Great sights, with one missing piece
*by J***P on February 20, 2013*

These are excellent bright night sights, but on some k-frame revolvers the included detent is oversized. If your handgun is one of the unlucky ones, you'll need to write to Mepro US at Kimber's Yonkers address for the smaller detent. Once you get it, installation is no sweat. The sights look great and work beautifully.
