Can you tell me what gun best suits me.?

g 19 is the best gun to carry because it is EXTREMELY lightweight. i'm fairly certain that's a 9 mil, and they're known for durability. plus they're pretty cheap. also might wanna consider a slightly larger caliber, because a 9mm won't always be able to kill someone (body armor, meth, etc.) and make sure u regularly go to the range to keep your skills up and also get a gun safe if u have kids
