Overall fire power goes to the 9mm, with 15/17 shot mags and lower recoil pounding the target with sufficient lead weight isn't a problem, I like the 40 and own a number of them. I've always packed the 40, but recently have moved to the 9mm for daily wear...much smaller and lighter, tho only 7 rounds on board with a single stack.

Do I feel "under gunned" ?, not in the least.
