Accessing my weapon while seated is like accessing my wallet while seated... difficult but possible. With a little pelvic adjustment, reaching, and effort, I am able to draw my weapon, but it's not easy. In fact, I often just take my pocket holster (with my KT P-32) to place it in my center console before I get in, and I put it back in my packet when I get out. Easy fix.
Actually, this situation is really common for me. I take a quick trip to the store at the drop of a hat and usually only grab my keys, wallet, and pocket holster (with a P-32, there's no reason not to carry

) Y'wanna know a really sticky situation, trying to draw from a Smartcarry while sitting... that's not really too comfortable or quick, so being in Condition 1 and aware of your surroundings is important.
