I would say Black Arch, but they decided they don’t want my money.
Don’t offer anymore and refuse to make a common gun+light. I even offered to send them the plastic from my last two holsters so they don’t have to do any mould work. I get it if they don’t stock a specific combo to mould with. I really liked their leather+plastic+mesh design. Really keeps sweat off the gun. After about 3 years now, I’ve rusted the hardware so much that it rotted through the leather. Some might say that only 3 years isn’t very good, but considering how hard I am on it, often soaked in sweat for 12+ hour days, I’m happy.
Looking at a crossbreed minituck now. Came to the handgun section for some current-market holster recommendations myself.
My problem with the crossbreed is that it doesn’t have that moisture barrier I’m accustomed to with the BA. I mean it when I say that I sweat like a sumbitch in the summer. For discretion and concealment, I’d also take off their stock clips and recycle some old ones. Don’t want the crucifix design to attract any eyes.
Otherwise, in general, for IWB, I think hybrid holsters are the way. I can’t imagine stuffing a full kydex holster in my waistband for all day wear in any conditions. I also don’t see the point in full leather.
