Question: Do u know if this will fit a S&W revolver model 17 ?
Document: Because I have small children I had a magna-trigger installed on my S&W 686. Because of the magna-trigger, I couldn't use my crimson trace laser grips anymore and needed something suitable for night use. These were a great compromise.
with these sights my 30 years old Model 66 got a new younth, it changes totally its potencial as defense weapon.
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.
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.
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.
Recently bought them for my ruger p345, and couldn't be happier with them, quality is excellent and make target aqusition much faster, so now I'm getting them for my s&w 686, and for my dads ruger p89
Im not a gunsmith or a gun nut, but I am a factory trained armorer for SW revolvers. Otherwise, I would have taken the sights to a gunsmith and been 5 star happy. Because revolvers are niche weapons in law enforcement nowadays, I dont get nearly as much practice on them as I do the plastic electric guns. Because I dont get as much practice, when work doesn't go smoothly on revolvers, my first reaction (usually correctly) is to doubt myself.
If its not a match, I will immediately send them away to a gunsmith.I'm sure I will see them again. The sights looked and worked great once they were on.
Finally, I went into our part supply and pulled a rear sight stock screw and found out the plunger hole in the Meprolight screw is the wrong size. Tried to replace MPL screw with factory screw and couldn't- they are threaded differently. So choices are to install without detent or have gunsmith rebore the MPL screw hole.I looked online and I am not the only person who has encountered MPL screws with improper holes.
Fantastic sights, but had trouble getting them zeroed in. I was pushing high right and no matter how much adjusting I did to the sight, it was still shooting high. I of course learned her habits and was able to print some pretty decent groups. As for the pros, they illuminate better than my pistol sights do. If you're old school like me, you'll really like this addition to your wheel gun. 1-10, I give these a solid 8.5
