I have a DA/SA pistol that has a good single action and a very heavy double action. It has a safety for cocked and locked, however, I manually decock and practice first shots in DA. When manually decocking, I can drop it to half-cock. Or, I can full decock and then thumb back to the half cock position. The half cock position makes for less heavy take-up at the start of the pull. Is there any reason that I shouldn’t carry it in this manner?
