Tip! After the screw is broken, slide the gun into a large clear plastic bag before taking the old sight out.. That way, the tiny spring and detent will be captured when it try's to launch itself across the room ( and it will.). Also, work within the bag when it's time to reinstall the detent assembly into the new sight. ( Again, it WILL want to launch itself). This will save time crawling around on your hands and knees (and maybe the whole project) 😃
I was on the home stretch, about to screw the sight in and I completely forgot the screw and plunger even existed and ended up pushing the sight back out and ping. That shit was gone. I found the plunger but not the spring yet. Lesson learned, don’t convince yourself for even one second that it won’t happen to you like I did. Lesson learned.
Just spent 30 minutes watching this and fitting a Brownells new rear sight blade kit to my 625 and it was made so much easier with this video: Thanks Brownells !!!
Here is a tip, when you are taking the screw with the detent out of the sight do it in a big zip lock bag. That way it can't go flying into the black hole. If you ever have one go flying good luck ever finding it.
Wish I had read that comment before I did this lol. I was actually able to find the detent and spring though by some miracle. They had even stayed together after their trip across the room into the shag carpet.
It took me a while because the old lock nut got stuck. I had to drill it out in order to get the old blade sight out. But ultimately I got it done and now know the procedure if I ever need to replace it again.
Guys! Don’t think for even ONE second that the plunger and spring won’t go flying. Doesn’t matter how much you pinch it down or try to cover it, it WILL happen. So don’t ignore it like I did. Put the rear sight base or the whole gun in a bag. You will be so sorry if you think otherwise. Trust me. It’s not worth risking it otherwise.
You can use the spanner blade to hold the nut in place and back the screw out from the other side (and reuse the screw and nut, when replacing the new blade install the blade and screw into the rear sight housing with the head hanging out and turn the screw until the hole in the screw head (that accepts the detent and spring) is just under the new sight blade and then back the screw off to expose the hole then install the spring and detent and with your thumb nail or small flat head screw driver a (appropriate sized straw) works great too and depress the detent and turn the screw head with your thumb and finger to capture the detent under the sight blade this is where the straw trick may be a better bet as you can (pre load the spring and plunger in a Ziploc if your not comfortable) then turn the screw head until the detent is captured under the sight blade and then slide the straw off and finish your install. Good luck, Glenn Promisco Gunsmith & Engraver.
Sir, can you provide me will all the part numbers for the tools that i need to do this job, including the vice... i have a smith 19-3 that needs a new rear blade... I have other vintage smiths that need the outlined sight blade as well
Generally once the nut is staked to the screw, you don’t remove it from the screw. You run the adjuster to the end of its travel and snap the head off. Then the nut and screw should be easy to remove from the blade. The screw and nut are generally considered disposable/one use, since you’d likely break off the forked spanner bit before you’d get a well staked nut and screw apart.
Got a brand new 629-6 that has a goofed up rear sight. The notch is lop-sided, and the painted white "U" is even more crooked. Disappointing. This gun already went back to the factory once to be repaired, as it was shipped in a completely broken, non-functional state. Double action mode worked, but the hammer and trigger were out of spec causing single action mode to be completely broken. Stubbing, hammer not staying back when cocked, hammer falling without pulling trigger. It was terrible. Thankfully the trigger mechanism was fixed by S&W. They replaced the hammer and trigger. But now I have to try and replace this ridiculous rear sight blade... again, dissapointing.
This was the best demonstration yet. Many thanks!

Sounds like a good plan.

I was able to change the rear site blade on my S&W K-22. Thank you! You're a life saver!
Excellent tutorial, thank you!
Thank you for doing these videos.
Thank you for watching!
Thank you for your video! It was very helpful!

Thank you!
There is a reason he says it looks easy getting it back in, it is really hard. That detent goes flying so easily. This is a job I hate doing!
So I’m currently looking for mine....where can I get a new one
@@paulmorang8340 MidwayUSA or Brownells or eBay

Steve-O droppin knowledge... i would love to be a fly on the wall in this guy's shop!
Easy when you know how ! Thanks for the video, made the job simple.
Thank you!!!
Much better than Midway's, which glosses over the infernal plunger and spring re-installation.
Nicely done! Thanks!

Tank you much Just did it BIG Help, first time, EASY THANKS TO YOU. ...
Thanks for the video! I will be ordering parts for the job from Brownell's!
Can you guys do a video on replacing a pinned front sight?
Great video!!
Thank you!

Does this really work?

where can I find that spanner wrench he's using to take the sights apart?
Smith and Wesson has different height rear sights. How does one measure the original sight to determine which sight to order ?
Hi, very informative video, love it! What size is the spanner wrench? Thank you
I used a #4 spanner bit
thanks
If the nut on left side is staked in place originally, how difficult is it to remove prior to changing the blade?
Generally once the nut is staked to the screw, you don’t remove it from the screw. You run the adjuster to the end of its travel and snap the head off. Then the nut and screw should be easy to remove from the blade. The screw and nut are generally considered disposable/one use, since you’d likely break off the forked spanner bit before you’d get a well staked nut and screw apart.
Hello,
Which Hunting Pin Model Do You Use?
Thank you.
These kind of videos dont need cheesey background music
How can I put my Smith and Wesson revolver brand new? He got some rust dots! Please anyone can help me? Thanks in advance
I made the mistake of snapping the screw with the sight stuck all the way to the left
I really wish there was a way to take it out without destroying that screw I just want to take it off to paint it pink and then put it right back
Does anyone knew where to get a new spanner screw I found the spanner but the screw flew Mach Jesus into the abyss of my carpet

The background music is making is annoying. It is unnecessary
Should have added a zeroing video.
I screwed up, I kept turning it CCW until something snapped, now nothing moves, what should I do?
