I used to carry my Hi Power cocked and locked as well.

Consider that one of the more popular carry guns is the Glock and the only safety it has is in the trigger. It is carried cocked and locked with an internal hammer and only a trigger safety. Most of the accidental discharges from them from what I understand are from people holstering them while they still have their finger in the trigger guard. Which you should never do any way.
