1. There is a concern about over-penetration with 10mm.

FWIW, I think over-penetration is way over-thought as a concern when a complete miss of the target would be much worse no matter what the caliber.

I’m getting the impression that the 10mm 230 grain is good for two things:
1. nailing big things like bears.
2. Macho bragging rights.

I now need to compare the Glock 20 to the 41. The ammo is about the same price, but I need to compare the 40 to the 45 regarding stopping power for humans. I need to stop by Cabelos and see what they have in 10mm too.
