I carry my 1911 style pistols cocked and locked (the way they were designed to be carried). Why lower the hammer on an SA pistol for carry? In a stressful situation one would have to cock the gun before firing, which is another unnecessary step. With the RAMI BD I decock so the hammer is at half-cock, and first shot double action, subsequent shots SA. Lowering the hammer on a live round can be done, but personally I never feel comfortable doing that. What can go wrong will go wrong and potentially ruin your day.
