Your situation is something I was concerned with when I started shopping for my EDC. I know some people think comfort isn't a major concern, but IMO, if it isn't comfortable, I won't do it everyday........thus defeating the purpose of CC. I've owned a Ruger P89 for years, and while some may be able to conceal carry one, I just don't see it happening. It's a brick.
I purchased a Kahr PM9 with a FIST Tuckable/IWB holster, as well as a FIST Pocket Holster. It will fit in a cargo short pocket, or even a front pocket in my case. Everyone has their own idea of what is important. Some are willing to exchange comfort for increased firepower or increased capacity. To each their own. Might I say if what you have isn't working out for you, try something different.
Someone mentioned earlier that sometimes they just carry their LCP. As mentioned on this site before, an LCP in the hand is better than hi-capacity .45 in the safe/car/bedside table/etc.
