Since you said you like the size/weight of your J-frame, and you sit a lot, an ankle holster will work well. Slow draw if you're not seated, but comfortable and accessible (unless you're not very ambulatory). You could put another one in a pocket holster in your suit pocket as well. Personally, though, I'd get used to IWB and find the right place for you. The Crossbreed Bellyband is very comfortable, adjustable, quicker than expected, and concealable. I wear it frequently, especially under dress clothes.
