Need a bit of advice on a gold bead front sight.

I am at the point on a .38 super build where it is time to do something about a front sight. I seem to do best with a gold bead.

I have made “gold” beads from 1/8” brass rod with a lot of satisfaction. Polished with #6000 grit. Been awhile now and they really don’t seem to tarnish. Time to step up to gold. I am making one because my high end guns with true gold beads are not to my liking. I have settled on a watch glass shape, angled up a bit, probably about 30 degrees. Oval but round in silhouette. Seems to catch more light, at least for my shooting.

Anyone here make their own gold beads of gold and can you offer your experience? Next question, posed by my friend, is why not concave rather than convex? Seems like the geometry would be marginally better.

Any thoughts would be appreciated.

Thank you in advance.

The gold line front sights have my interest. Pics are posted in other threads where they are flush, serrated, but I'd go for a polished convex configuration, the gold line being slightly proud of the sight blade.

I'm not a jeweler or precision machinist. However we are a long time user of gold bead front sights. Our experience has proven, to us at least, that the top of the gold bead should be even with the top of the front sight blade. If the bead is below that level, at speed the shots tend to go high as one's focus is on the bead and not on the top of the sight blade, which is usually how one zeros the sights. Does that make sense? See the link below for clarification.

We are following this with great interest.

Makes perfect sense to me.

I started to mod a standard front sight to add a gold bead. I bought a pair of gold bead stud ear rings. 1/8” polished Gold ball. Unfortunately the balls were hollow and in manipulating them to install, they collapsed. I ended up buying beads from Scott Mulkerin http://www.sdmfabricating.com/
They are flat faced. In the build attempt the ball shape was much brighter until failure. If I was making them I would definitely use a domed shape bead.

For sure the bead needs to be solid gold and not hollow. Been looking and the closest I have found are gold studs for body piercings. They, the balls, come threaded and then a separate bar needs to be modified to use the system as a front sight bead. Haven’t pulled the trigger yet on the idea. No pun intended…

I have found that a domed oval, set at an angle such that the oval appears round (viewed on a horizontal sight plane) works best for me. In that I have a fair amount of time in this 1911, I am going to try it. If all else fails, I may call an old dentist friend for some advice. Should be able to braze the dome to a steel Novak cut blank from Harrison.

My eyes have changed over the years. More reflected light seems to help. I want it to glow like the sun if at all possible.

I think you're onto something.

Brass is fine as well. But try to get the top of the bead as high as possible.

After you make a prototype. Try to get someone like Dawson to make sight blanks, and boom, you're a sight company.

I'm just as happy with brass as gold - takes ten seconds of polishing time to time. But I definitely like either in the domed shape, seem to catch a bit more indirect light for my 64 year old eyes. The flat-faced sloped beads do OK, but I think they rewuire light falling on their face, or at least so seems to me.

Fermin Garza's Sight for a Ruger Single Six. Fermin threads his beads into the blade and the top of the bed is even with the top of the blade. Bead is brass not gold.

Well, I got back on the SDM website (sdmfabricating.com) and decided to order one of their gold beads. The order process took me to PayPal, which is very secure.

I ordered the gold bead on April 10th and received it today, April 14th. Very fast and the bead is exactly as advertised. I am very satisfied with the transaction and recommend SDM to others on this forum.
