I am 5'11" and 250lbs. I find it very easy to conceal anything. I have carried 3 decent sized handguns with casual clothing before and I could easily do more with all the right rigs. I will usually carry a xd357 at 3 oclock strong side iwb.
when I first started trying to conceal I was nervouse and didnt think I could easily do it but after trial and error at the house I found ways to carry and figured out how to present myself when packing and what compromises to make. A lot of it is being self conscious that you are printing just becuase you are aware of it being on you.
My own family cant even tell when or were it is anymore without patting me down so its like I dont even have one unless they ask me which is always a yes. Now they just ask me how many.
