the springfield XDM45 has a much smaller grip than the glock 21 and also has replaceable backstraps to make it even smaller. I have medium to large hands and use the medium backstraps with my XDM45s but I would wager that the small backstraps would serve you quite well. you may also check out and see if the FN Herstal FNS is offered in 45ACP as well, they are very nice guns with good grips.
