rjay, I am a big guy too, 6'4" 300 lb. and have a bit of a gut. I have carried a lot of different weapons over the years and the most comfortable holster that I have found in the past 10 years is an IWB hybrid holster. My main holster is made by Kholster out of St. Louis, and I have 4 other holsters made on the same idea (CrossBreed Super Tuck; DeSantis and two others that their names escape me right now). I keep coming back to the Kholster because of the fit, the warranty, low-cost, and the absolutely pure comfort with the carry. You can order them for just about any gun ever made. You can cut the leather to suit yourself on the fit and it does not void the warranty, lifetime, no strings attached warranty. I have probably sold 100-175 of them to friends (I didn't actually sell them, I sold the friends on the concept, they bought and they like it) and patrons of our private range in the Ozark Foothills of Southern Missouri. It gets hot here, and us big guys know what it is like to 'perspire', especially in August and September, but I never have a damp pistol or revolver that I carry! The Kholster's thick, pliable leather keeps me and my gun comfortable. I wrote a review on the Kholster on USA Carry a couple of years ago... Try it, you'll like it!!
