Also on carrying a live round in the chamber.
I saw this somewhere, cannot remember where, but a fella got a piece of leather that would fit between the hammer and the firing pin.

This piece of leather was thick enough to keep the pistol from firing.

It was attached to the holster. So when he drew the pistol he would pull back the hammer just a little to release the hammer's grip on the piece of leather, then he would cock the pistol.

This was not done for a "fast" draw, but so he could quietly draw a cocked pistol in the field.

Ie. not have to "rack" it to chamber a round.
