Depends. When I pack my Browning HP I carry it on half cock chamber loaded. If things look like they are getting crowded and a gun grab is possible, I simply slip the safety on. If someone does get the BHP(I am not as young and strong as I once was) I want to see then try to figure out how to shoot the thing, while they are so engaged I have my 940 in a left front pocket for amusement.
Recently my agency has gone to the M&P full size .357 with thumb safety. Carry pretty much the same way locked an loaded. When the weapon comes out the safety comes off-always, and the real safety takes over. I know that if I want to stay for a couple more pension points I will probably have the switch to the M&P, but it really is a very good weapon. The 940 will stay however, or maybe my 632 Pro.
