Welcome aboard. I am, how shall I say this, a fat boy!! I have found IWB to be pretty comfy. I'm about 6'2" and 230ish. I have a Sig-Sauer P-239 that I carry with a Crossbreed Supertuck and sometimes, I carry my wife's S&W M&P Shield in a StealthGear holster. Both weapons conceal well under my regular summer outfits of cargo shorts and an over-sized t-shirt. I'd say 90% of the time I am carrying the P-239.
