I'll be the first to admit that I'm a newb when it comes to firearms. So I'm sure I'll catch some flack on here, but what ever. I'm looking into purchasing my first firearm. I'm really leaning towards the Beretta Cx4. I'm just not sure what caliber to get. It is gonna be mainly for defense and maybe some hunting. I'm just looking for a few pluses and minuses with each caliber it comes in. Hopefully some people that actually own one will help me out.
