More and more lately I have been thinking it's time for me to pick up my first handgun. I am not a total n00b when it comes to firearms, but I nor does anyone in my family own a gun. I used to have a membership to a indoor range for a year where I would shoot about once every 1-2 weeks with guns I rented from the range and I go shooting with my friends frequently but we're usually shooting their shotguns, AR's, ect. This gun would primarily be kept in my house for home defense and I would eventually like to use it as a CC. What are some guns/calibers I should be looking into and what should I be looking at price wise? New or used? Any help would be greatly appreciated.
