Of your choices I'd be inclined to go with the EMP.
My SR40c seems to be seeing a lot of holster time in the woods lately. Plenty of power in a convenient, non-cumbersome package that allows you to do things other than carry a gun.
EMP, Glock 23, M&P40c, 24/7 G240c, any of them would make a nice packin' pistol IMHO.
And bring some spare ammo for the spontaneous plinking sessions sure to arise!
