I am thinking about getting my conceal carry permit and am looking for a gun that I can carry with me predominantly in the vehicle with me more than anything, but also to have at home in a drawer so overall size of the weapon isn't an issue. I have a 9mm, but I am curious of what people think of that as a self defense style weapon? I am considering buying something bigger, nothing fancy, just something that I can have with me for extreme circumstances. Anybody care to shed any light on the situation for me? Thanks for your help.
