RE: 9MM
Never used it with deer, but carried it while Archery, just in case a Bear made there presence.
Low and behold a bear showed and arrowed him, then he ran 25 yards and pulled out the 9MM hit him twice and never phased him.
The next week I had a .44mag.
Took a nice 8 pointer in his tracks with the bigger bore, why chance it?!!!?
Ruger super redhawk 10" barrel, iron sights, maybe a scope in the future
