This is a better version of the same sights I posted step files of a few days ago, but this time, I put in the STL's you'd want to just print, and an open top version of the front sights also. I don't know why my dumb ass didn't include the STL's in the first place.
The step files include deliberately-silly reference geometry (for example, the bolt and nut pair to hold the front sight on, is a single solid piece, but modeled as if it were a slightly too small diameter and too long anyway, and the front sight post is comically too long), but the geometry should make it clear what you need to do. The front post threading is 3/8" standard imperial thread size (coarse pitch), and you'll need to cut slots lengthwise in it for the detent tooth (1/8" diameter, or 3.5mm) to sit in and lock it in place.
The way you use threading that is the wrong size, is 1) you heat up the end of a bolt with the threading you DO want, while holding it with pliers, and then 2) while it is still hot, and being careful to hold it straight, you screw it into the hole that was the wrong size before, and allow it to cool there.this will cool and shrink the parts and let them separate but leave a clean threading surface on the interior of the hole you want to use.
For the all-black gun look, you are supposed to 1) print in all black, 2) blue the front sight post after you machine it, 3) used blued or black anodized/painted hardware, and then for sights visibility you should paint the inside of the cup of the rear sight and the very tip of the front sight post with some kind of a hard enamel paint, like a nail polish, and you should possibly also sand, wash, and degrease the surfaces you want to do this to first.
