Broken rear sight model 57

1911daily · Jul 5, 2017

I removed the rear sight many years ago, to install a scope. I have decided to return to sights once again. I had the sight in a basement and through dampness, only the blade got rusty. When I tried to turn the screw to hopefully remove the blade, I believe the screw broke inside. I am not going to attempt to repair it, however, I cannot seem to locate a new rear sight. It is a blued model 57, 8&3/8 barrel, mfg in 1980. I tried calling S&W, they sent me to Jack First, who no longer had these in stock. Should I simply send the gun back to Smith & Wesson for repair ? I have been to many gun shows and have not been able to locate a new (or used) rear sight for this type of "N" frame revolver. I would appreciate any input. Thank you in advance.

Keep all the parts. You can get a new screw and nut and blade if needed. They are not that hard to fix. Way easier and cheaper than trying to source the whole thing. You can get the parts from Brownell's for a few bucks.

What Toolguy said^^^^^^^

Brownell's should have what you need. If not, Midway USA.

Here is a link to the parts you need, measure the "slide" (blade) height and you should be good to go if it is in stock:

As others have posted Brownell's and Midway usually have the blade, screw and sight nut needed. I have recently purchased those parts online to replace a damaged rear sight blade on my pre model 27.

Soak it in kroil for a few days while you're waiting on the parts. I have a feeling the rust is inside as well.

Just a recommendation. When you turn the windage screw out to remove it do it "Inside a large clear plastic bag". The teeny tiny spring and detente have a habit of flying out to places unknown and never to be seen again. The bag should contain the parts for you.

Breaking the screw is actually part of the procedure for removing the sight blade for replacement. You turn it one way til it breaks and you remove everything carefully to replace with new rear sight blade. You turn it the opposite direction and the screw breaks.......only you cranked everything to the cylinder release side of the frame and it pretty much seizes there. I know because I've done it before hahaha. What I and one of my best friends did was put a very thing high quality bit in his fathers old drill press. Holding the assembly only (removed from the frame) we drilled out the end of the screw from the middle of the nut (see left side of photo) and wiggled the remainder out slowly. I also put a link to how to reassemble new nut, screw, and sight blade with your old spring and plunger which are minuscule to say the least. Good luck. - Joe

Rear sight blade, screw and nut that fit into your rear sight blade leaf.

According to the chart of common S&W revolver adjustable rear sight blade sizes your model 57 with an 8 3/8" barrel uses a rear sight blade #04073 that is .160" in height.
