Hi I’m Dylan..I’ve been carrying my S&W Shield in .40 cal for some time now with 165 grain defensive hornaday rounds. I carry it in an uncle Mike’s neoprene IWB holster for a few reasons. 1. extremely low profile. 2.if you don’t have anything holstered you can’t tell you’re wearing it. 3.very comfortable at my 5 o’clock 4.and they’re inexpensive. I also carry a Ka-bar at my 4 o’clock for every day use and defense.
