When one carries a J frame or any handgun in a pants pocket, that pocket has nothing in it except the gun and the pocket holster, preferably a very thin, simple holster like an Uncle Mike's.

No coins, pocket knife, thumb drive, chap stick, pen, chewing gum, candy, condom, rabbit foot, NOTHING. When you stick your hand in that pocket, all you want to come out is the gun.

Don't follow my advice, I've only pocket carried for 20 years.
