Im sure there are many left handers out there and my buddy, just bought his first gun. A Springfield XDM 9mm (4") for his CHL carry. He starts his class on Saturday as a complete novice. Can some one give him advice to their favorite conceal position, and holster for a lefty. His job has him in suits everyday, and jeans and polos on the weekends. Thank you for advance, and if this is a repost question I apologize ahead of time.
