1911 installation of gold dot front sight.

Need suggestions for a gunsmith who can install a gold dot in front sight on series 70. I believe they use the existing front target sight, 
Thanks in advance

An engraver might be what you need.

Most smiths use a dovetail front sight that already has the gold bead front sight installed. Sights are about $80 plus installation requiring cutting a dovetail into your slide. If a custom gold bead was installed in a stake on front sight,  most likely a new sight will be used to install the gold bead then staked to your slide.

If you want to drill a sight blade, MIL spec circular electrical connector contacts come in several sizes and can be cut and glued/bonded in. The plating is very good.

Shown below is an Amphenol AT60-202-1631 AT/AHD Size 16, Gold, 20-16 AWG, Male Pin Terminal

The front sight is on an older Clark,  it is not dovetailed, it is milled and set screw tightened from the from of the slide.  I did contact Clark but have not heard from them.

Shotgunners use gold bead sights all the time, I looked for them on Brownell's once and found a bunch. I'd think any gunsmith could drill a recess for one in yours.
