I'll third- it's my OC holster. I seldom OC, but when I do, it's with a Serpa.
I fourth. I actually find that it's not only more comfortable but because of my size I can CC in a Serpa. As long as I'm not trying to carry an SBR or wear a skin tight shirt it poses little issue for me to carry at 3/4 o'clock. My larger arm blocks view of most printing and it is in general comfortable. I personally recommend the Wilderness Instructors belt reinforced, it's very durable gives a great deal of support. Also, I don't use paddle holsters ever, with my size and the movement of my body they break free of the belt, not to mention I find with retention holsters if they aren't seated 100% they can and will move causing draw issues.
For the larger guys, this recommendation was made by another bigger guy. And for anything firearm related training, he's the guy you need to listen to. At least IMO.
