I have a few questions regarding ammunition in general. What does the grain refer to? What does it mean when someone says that they carry +P ammo? What are some recommendations in 9mm for concealed carry and home defense? What are the basic categories of 9mm ammo that is available, e.g., hollow point, etc. and what are the advantages/disadvantages of each type?
I am sorry if these questions seem basic, but I guess everyone had to learn this stuff for the first time at some point. Any information that can be provided would be greatly appreciated.
