I've been pocket carrying my BG2 for 9 months. My choice of pants is important for comfort, concealment, and ease of withdrawal.
I find my jean style pants with smaller tighter pockets work, but my BG2 inside a Muddy River Tactical kydex prints slightly and is more difficult to withdraw.
My Dockers style pants are more loose fitting, with 14" larger deep pockets on the side rather than in the front, completely obscure the shape of the holster and grip. If someone is looking VERY closely if I'm walking, the shape looks like a cell phone. Withdrawal is very quick.
