Comfort vs convenience
There is going to be a argument with your body between comfort and convenience whenever you put on a holster. IWB may work for you, but if you start carrying larger guns you’ll start to feel it pretty fast. I have already seen guns go from carrying fat compact guns and transitioned back to a 1911 which is longer, but is thin and more comfortable to carry IWB. If you are expecting to get into street combat then do something other than wear a concealment holster. I have had years of experience in carrying guns IWB, but recently I’ve gone to pocket carry because I’m getting tired of feeling it when I’m out on golf course or batting practice.
There are plenty of custom holster companies for you to research, but you may spend a lot of money on a holster that doesn’t work for you and the best thing to do is go to a gun show or a gun shop that carries them and ask if you can try them on. Galco holsters have a stow n go holster that is an easy fix for IWB concealment holsters. If you don’t want to blow a ton of money on a holster look at Galco or Don Hume first. There are belt loop, paddle and pocket holsters that are very reasonable priced.
