Sounds like you are quite comfortable with your new found skill,... maybe a little advanced challenge with some,... ' do-it-yourself ',... white dot sights, with a drill bit and white paint, could be in order? But, I wouldn't try it without a drill press, or a reasonable facsimile.

Unless you feel confident enough with a punch and hand drill.
I like a vertical center white line rear sights, in conjunction with a white dot front sight,... a triangle file works well for that. I like to file away at an angle that produces a 1/8" wide line at the top, that tapers down to zero, at the length I want. Doesn't take much time at all!!

But, you do have to pull the rear sight off, to be precise.
