In order (N.B.:
My opinion):
- 10mm: Overkill for an SD sidearm, unless you want to load it down, then what's the point?
- 357 Sig: 9mm on velocity steroids. Concern there is over-penetration.
- 40 Super: Don't know it, but ammo selection/price might be a concern?
- 45 Super See above.
- 45 (ACP, I presume): I like it for a home SD round for its lower likelihood of barrier (wall) penetration
To my way of thinking, same as it was when I first chose it, the .40 S&W hits a sweet spot: Improved terminal ballistics over 9mm and better barrier/garment penetration w/o quite as much over-penetration risk as more powerful rounds.
I might be inclined to a 10mm for carry in the woods. In fact I'm vaguely considering it. I use 45 ACP for the home defence pistol. I will soon have a 1911 in my carry rotation. I
may end up with a 357 Sig in my carry rotation (but only because I can--not so much as I need to).
