Pocket carry, pocket carry, pocket carry. A great solution for "Big Boys" in any weather.
I carry my Walther PPS 9mm in a Done Hume pocket holster in my front pocket, in plain old Wrangler jeans or in any style of shorts with a front pocket. I don't even know that it's there. I carry an extra 8 round mag in my other pocket.
When I am wearing large shirts, untucked, or cover garments, I can step up to an assortment of bigger/badder guns, but the Walther works in the front pocket.
You can get the PPS in .40 S&W.
