A pocket holster also disguises the outline of the gun and does a pretty good job of keeping it oriented appropriately in your pocket.
Don’t believe that your trigger is so hard and long that it is safe with no pocket holster, don’t pocket carry without a pocket holster.
Don’t pocket carry a gun with an external safety and expect the safety to stay on.
Obviously some guns are not suited to pocket carry at all.
Take a class, research best practices. It is your responsibility to carry right or don’t carry.
Don’t run with scissors, don’t spit into the wind, and don’t piss on an electric fence.
Keep your class, you need it.
