I've tried about everything, and I use an MTAC.
The VM2/TTGunleather type holsters add WAY too much thickness to an already fat gun. The 2 points of contact really distribute the weight well, and the MTAC/CBST/Theiss holsters add minimal thickness. I can pack around my GEN 4 G21 all day in my MTAC and it's the most comfortable holster I've tried. Being modular, unlike the CBST/Theiss, you can just change out kydex bodies to carry a different gun. If you don't like it, they hold value pretty well, and won't take long to sell.
GEN 3 20LS/20SF/21SF/30SF/23/34/26
GEN 4 17/19/21/34/35
