If your main purpose for this handgun purchase is a backup gun for hunting hogs skip both the 9mm and 40 S&W. If you must have a Auto then as already stated above get a Glock 20 in 10mm.
You can't get what your looking for without a little recoil and the Glock 20 is pretty mild compared to some others in the same caliber.
If this were for SD/HD then either the 9 or 40 would be great.
I am not a fan of "Big" recoil like what you see out of full bore loads out of .357mag snuby's but, medium recoil out of larger, heavier auto's is not so bad and I have gotten used to it.
