I am not going to get in to the legal/soccer mom/etc. angle, since it's been mentioned a few times here.
I would like to see a HGH simply because it would be a welcome change and a new challenge. There would be pros and cons to hunting with a pistol rather than a rifle.
First the pros:
-Lighter
-smaller (doesn't get hung up on fences, tree branches, etc.)
-easier for mobility impared and physically disabled hunters to use.
-adds extra challenge to a hunt.
-easier to use in a blind or stand. (compact size)
Cons:
-Harder to hold steady and less accurate over longer distances (increased danger to hunters in the area)
-'scary' factor with joe schmoe and law enforcement
-obviously the biggest con is; that current laws and restrictions prohibit it, but, again, that is the original purpose of this thread, so I digress...
That was just off the top of my head, so if anyone has any more to add, I'm all ears.
