1" tighter, pretty uncomfortable, and fairly difficult to pull from holster.
MTAC holster, its broken in.
Undershirt works well, warmer weather on its way, 2 shirts, not going to work for me. Right now its great, warm weather, not so much.
Ive thought of moleskin stuck to the holster, old t-shirt or jean chunk sewn to it as well. Moleskin seems lowest maintaince. Likely just change it every few months Id guess.
