The Glock 42 lends it's self to a billfold type holster really well. I prefer the rear pocket carry. If carried in a front pocket I do not think there would be much difference. I would carry a Body Guard type J or a 642 in a front pocket without a holster. If I pocket carry a Glock it's going to have some type of pocket holster covering it or I won't carry it. Just too easy under stress to get ahold of a Glock trigger and get a discharge accidently IMO.
