Default Rear Sight Question

A few months back I picked up a pawn shop orphan mdl. 15-6, 4". I was told that it was an ex-Alabama prison system firearm and, based on the well used condition, I don't doubt it. The rear sight blade is chewed up on one side so I'd like to replace it.

I understand that the screw and nut will need to be replaced as well. My question is in regards to blade size. Numrich shows a .126 and .146 size. Is this the notch size width or height? Or is my assumption completely wrong and it's some other measurement.

Thanks in advance for your assistance!

Measurement shown is the height of the blade. The S&W parts book shows the model 15 4" as needing a .126" blade.

Brownells and Midway also have blade/screw/nut replacement kits.

You can move the undamaged end of your rear sight off to the side so far that it sticks out then measure it.

Before I bought a replacement I'd fire the gun as is then get a higher or shorter blade to get point of impact where I want it. For example, if you have to elevate the existing sight way up then switching to a higher blade would give you the option of sighting in for long range.

When replacing sight slides, before staking the nut on the screw, I take it out and shoot it just in case a different height slide is needed..

Saves wasted parts..

Thank you all for the information. I just measured the height and it is .126. It shoots perfect on a 6 o'clock hold, so that's what I'll order.

And thank you armorer951 for the link. I had no idea that there were kits available. That's about half the cost compared to the individual parts from Numrich.

Over time there have been about six different height rear sight blades to accommodate the full range of 2 1/2" to 8 3/8" guns. Helpful hint: take the rear sight apart INSIDE a gallon plastic bag. Several small parts in there to go flying and get lost. Re-assemble likewise with the new sight blade INSIDE a gallon plastic bag. The "pickle fork" tool for working on these sights is delicate; use a judicious amount of force with it.

thanks for the bag tip. I always keep spare detents and springs.
