If you are carrying without a round in the chamber, you may want to rethink carrying. I mean this in a constructive way not critical. These are very small guns meant for close range encounters. This is a OC forum so the assumption would be you plan to OC one. Still, to draw and use your other hand to rack the slide assumes you have space and time. Many pistol battles take place at very, very close range and the distance opens up as both parties scramble for cover, and move away from the incoming rounds. Do you honestly think you can draw, load & fire (accurately - under stress) while being attacked by someone who may be at ams length? The TCP has no safety (as most pocket guns don't)...so if you are CCing one (which will take longer to draw usually) you need to use a decent pocket holster & wear clothes that allow for a easy draw. Just my opinion, but carrying any pistol in a condition that requires a two hand loading action while drawing and getting on target, is really pushing ones luck. Good luck & stay safe.
ETA - carry TCP(s) & other pocket guns loaded with a round in chamber. These pistols use long trigger pull (TCP/P32/P3AT/LCP) to act as a safety to prevent unintentional firing. My P32 has such a stiff slide spring, I doubt if I could rack the slide under stress without knocking myself out - if my grip slipped.
