Recently I took the gun safety course and am awaiting my Concealed Carry License. My grandfather gave me a .45 Glock 21 and a side holster for open carry but the instructor told us to never open carry because it makes you the first target if they know you are armed. I am new to guns but want to concealed carry my Glock. I am 6'6" and a bigger guy. I weigh about 380 and typically wear around a 4XLT shirt so that it is loose fitting. I need suggestions from the people who have Concealed carry a Glock on what Concealment Holsters and setup I should be looking into. Thank you for your replies everyone.
