RE: 9mm enough?
Just a personal thing, but I cannot stand a 9MM. I used a .45 for years in th CG (still do) and was very unhappy when they changed over to th 9MM.
The .357 should be O.K. for hunting if equipped with a longer barrel than those you would ordinarilly see for personal defense, they were the rage back in the fifties but died out when the .44s and .41s came along.
It is a bit strange, here in Ga. they just changed the handgun rules to where you can use ant center fire including the 9MM, but I can not legally use my black powder .44 Walker even though it is a lot more gun.
