I am not sure how I missed this! I have one of the BD 9mm guns and it is very good. In my opinion it is the best of the "choped and lopped" duty guns that came out in the 90s and 00's. It points well, has a decent DA/SA trigger that can be made stupid good with a little love and money, and they are just tanks of a gun. They are based on the Colt Z40/CZ 40B pistols that were designed to be LEO/Duty guns until Colt went bankrupt and pulled out of the deal. You can even find some of them in .40 if that appeals to you.
There are some downsides though. Its a heavy gun, it is fairly thick and it is a somewhat dated design. Before I switched to the 365 in 2018, I carried a CZ 75 Compact over the Rami. Same weight, more ammo and a bit more to hang onto. But the Rami is the best of its very narrow breed and one of the best IDPA bug guns. Compared to things like the Hellcat though, it really shows its age.
I was about ready to send mine off to have the slide milled for a dot until I heard about the 509C MRD. I very much prefer that gun for a "medium duty" gun. I would suggest taking a look at that gun as well.
