New to conceal and need some guidance on full size carry

So I've decided to finally conceal carry. I'm a bigger guy ( almost 6'4 and 290lbs). After messing and trying different setups I've decided on carry owb and carrying a full size.I got a sig p320 and a Blackhawk omnivore with a rail light attachment. I own a coffee shop and get in while it's dark and leave when it's dark so having a light and something I can grab was a must.What are some tips and tricks for carrying a full size owb and also help with minimize printing. Thank you so much in advanced. via /r/CCW http://ift.tt/2Fcf2zm
