I do this......here lately I've been switching back and forth. It depends on what clothes I'm wearing. I prefer a one-handed draw you see. Pocket carry is great until you sit down....then it sucks. So if I'm going to be sitting, not going to pocket carry.
I actually have three holsters I use right now: pocket, strong side OWB, and shoulder holster. I don't always carry the same handgun though.
Now pocket carry CAN work for sitting.......if you carry your backup on your ankle. Then it works just fine! Just go for your backup.
