For years Bo-Mar rear sights set the standard of which all other rear sights were judged, so why not make a fixed rear that uses that knowledge. Dave Dawson set out to improve on that and make the best fixed rear sight on the planet for competition and target shooting. The blade is back angled 3 degrees to reduce glare. The notch is the deepest available, providing more visual reference for faster precise windage alignment. This also gives the shooter the advantage of tracking the front sight better during recoil and placement on target, for those tight hardcover shots. The serrations on the black sights are designed to draw your eyes to the HiDef sight notch, providing a clear, crisp sight picture, yet snag free on outer profile. Chamfered to break all sharp edges and not rub you the wrong way.
Loctite is not included so make sure to grab some Loctite 262 Threadlocker. Works on front and rear Glock sights.

I was expecting the angle to be a little more dramatic, profile was pretty close to the factory rear but better. I like the all black rear and the 140 is great even with the stock front. I got the rear first to see how short I needed to go on the front (factory sights I needed a shorter front, I wanted to get on paper first with dawson rear & stock front then decide on front height) Quality is good only took a lilttle filing and the included punch worked great.
Had been using stock rear sight w/ Dawson front fiber optic.
Got the .135 notch rear & it is a huge improvement, much
quicker sight acquisition.
I added this rear sight with a .140 width and FO front .155 height. I'm older (54)and the extra width allows light on the sides of the front post allowing a clearer sight picture. As long as it's a nice day these are great. I really think it is worth it to spend $10.00 more and have the FO version. If you have clear vision though these are excellent as my younger friends tell me.
