I want to get a McMillan inletted for a Badger style DBM, who have you guys used? I know McMillan and Redhawk do it, just wondering if there’s anyone else I should check out.

I've had McMillan do it and would easily go that route again. Cost to quality is a bargain with McMillan.

Badger ordinance themselves does it:

The last McMillan gamescout I bought used was inletted for BDL and I wanted ptg stealth in it. Broke out the files and Dremel and it took all of 15 minutes. Slowest part was grinding down the pillars to proper height. It's not difficult, just take your time and keep checking the fit.
