    I picked up this cute little 1849(?) 31 cal revolver from a buddy awhile back. It has a .32 S&W conversion cylinder with it and that is the only way I plan on shooting it. Took it out a couple of times and found a decent hand load. the bad part is that it’s hitting a whole target high! It’s not going to be a target gun by any means, but if I do carry it out in the field, I would like for it to hit close to point of aim, especially since anything I’d be shooting it at, would probably be pretty small! So, I did the math and I think the front sight needed to be about 1/4” taller than the factory tiny brass cone. I found a Marbles rifle front sight in the parts box that looked like it should work. Pulled the barrel off of the pistol and locked it up in the vice with lead jaws. Did some measuring and marking. Initial cut was just under .300” wide and about .100” deep. Cut that slot out with a jewelers saw and started filing it. Got it pretty much to depth and then started the dovetail sides with a triangle file with a ground safe side on it. Doing this on an octagon barrel makes it a little easier because you can eyeball flatness and straightness much easier than on a round barrel. Lots of filing and checking and was able to get a good, tight fit. I also depend and widened the notch in the hammer (rear sight) and the bead fits in there great. The dovetail needs cleaned up a bit and I’ll cold blue it under the sight. Also the front sight will need narrowEd up to look better. The tip of the hammer has a good bit of material, which is probably useful for a cap lock, but not needed for a center fire cartridge gun, so I can file it down a bit more if need be. I also have some silver wire roughl 1/16” diameter so I can solder that on the top of blade if I end up filing the bead off of this new sight. In all it took about 90 minutes to do the work. Since I have no milk available it’s good to be able to do things like this myself. I can’t say I’d do it to a thousand dollar Smith revolver, but for a cheap little plinker like this, I’ll risk it! 918AD11C-63C3-4D90-92E1-BA522C3EAF4A.jpeg 1010A308-6F48-4144-B5D4-E6928208BFCA.jpeg 79FBF8EE-0734-459D-B426-8FA5B7652D00.jpeg CA64601E-266F-4E26-BDBA-B154CA8D6988.jpeg 89099879-9AC5-466D-82C1-4D62913950EA.jpeg 314A2564-F8A3-4E97-9E7F-34742237B813.jpeg 0B064D35-0AC7-484F-9E20-5187EFBFB384.jpeg BB9516D1-8F4D-4CC2-9A98-6AFAACA966D2.jpeg A244A467-0917-4B9A-90A6-35D12F3A46DA.jpeg

    And, yes, I know the sight isn’t centered. Also, I don’t know why the pics are rotated 90°. It happens sometimes and not others. No idea what I’m doing wrong.
    Classic! You can hand tune a piece of metal from the 1800's but can't figure out a phone made last week. Lol! I think it looks great and applaud your work. I think you figured out the hard part the rest is just a matter of time/finishing.

    EXIF metadata from your camera. Some graphics programs can remove this. I use FastStone Image Viewer to remove it from image files.
