I carry all 3 of my carry guns in Appendix IWB. I'm 6 feet tall and 145 lbs, so I don't have much other option for concealing on my belt.
I'm a big fan of High Noon holsters. Their straight drop holsters work great for me. They're around 60$, depending what model you want. The tuckable ones are nice if you need that feature, but the non-tuckable is a little more stable on the belt.
My daily carry setup is a Smith and Wesson 3913 in a High Noon Alter Ego. Very comfy.
If it matters to you, High Noon is based in Tampa, FL. Everything is manufactured in the US, and they have pretty fast turnaround time. Their satisfaction guarantee is pretty good too. I like the company. I have a belt and 4 holsters from them.
