I don't know if you've considered CZs, but the ergonomics are very much like 2011s. A CZ Shadow-2 optics ready will tick all of your boxes, while an SP-01 will tick all but a factory cut for optics and be cheaper. I would imagine you can take them down one-handed if you had something to push the slide stop mounted on your bench. Barrel length is 4.9 inches or so, so may be larger than you want.
