Other solution I would suggest would be to call Springfield Armory's customer service and see what they suggest.
P10 would be too small. P12 will almost
work, although it seems to have two problems on the ultra-compact. First, it looks like the screw holes are on slightly different centers, and second, there's a difference at the rear of the grip--hard to explain, but it seems the Springfield has a bit more metal back there.
