Pocket holsters have been recommended above because bumping into a stick, or a steel rod, or anything else small enough and stiff enough to push on a trigger through the pants fabric can cause a discharge in the pocket.

A proper holster will prevent a situation where a trigger is pressed externally through the fabric by a device.

I've read of news stories and threads from various forums where people without a pocket holster learned that hard way.
