Glock 19 with Fitted Clothes?

I'm looking into buying a Glock 19 for carrying. I currently have a Beretta 9000 in an uncle mikes holster that I carry in the 12:30 position. (I hate this set up so much, crappy gun and crappy holster but I'm gunna buy a new gun and holster soon.). I'm 5'9, 155lbs (not fat, not skinny, just normal) and I conceal my 9000 pretty well with minimal printing, and I wear slim pants and pretty fitted shirts. I want to get a T-Rex AIWB holster for the 19 with the spare magazine holster built in. I'm currently wondering if you guys think I'll conceal the 19 just as well? I don't want to change my wardrobe and because this 9000 is the only handgun I have I'd like to get a gun that's a good first real handgun and good for concealing. I got this 9000 from my dad along with the holster just because he didn't care about it anymore and so I just took it but I'd really like to get a good gun. So I'd love to hear feedback from you guys. I've never posted anything about concealed carry so if I missed anything please tell me. I'd love to hear what you guys have to say! via /r/CCW http://ift.tt/2q1rxG8
