Im torn between the 10mm and .45. If I had the money, I would get both, but thats not going to happen right now. I want something for personal protection to carry with me (I know there full size and thats ok). I also go hiking/camping a lot and i know the 10mm would be perfect for that. I guess my question is, how many people think the G20 is overkill for self defense against another person?
