Well, since I use to own a Glock 29 in 10mm, and it is the 'sub-compact' I would think durability would be no issue. They still make the 29, as far as I know. I just feel basicly a Glock the size of a 19, with a slimmer grip in 10mm with 8 or 9 shots would be a bit more comfortable than only 7 .45s. I doubt a full house 10mm kicks alot more than Cor-bon 200gr .45s from the same package.
Since I also own a Colt Defender in .45, and it has a thin frame, I would not worry to much about recoil. If you can handle one, you can handle the other.
