I wear pressed slacks and a button down or polo to work with no coat, so I usually don't carry my Glock. I keep my LCP in my back pocket with my wallet, no holster. I am 100% confident that as long as my finger is not on the double action only trigger, that it will never go off. You may feel more comfortable carrying in your pocket with a wallet type holster. If you are wearing a suit I see no reason to not carry a glock iwb with a Theis or similar holster.
