In what reality would a long drawn-out firefight between me and a bad guy happen often enough for me to be "seriously inconvenienced" by the fact that I only have a 10 round clip? Does that ever actually happen?
The only way I can see that happening is if I'm wildly firing rounds towards a target hoping something hits. Not very realistic.
If you were talking about just yourself - I cannot really comment since I don't know you and have no idea what happens to you.
For all I know there are millions of people who don't own a gun at all and don't feel inconvenienced by that at all. If you don't need more than 10 round magazines - just don't buy them. If you decided that 6 rounds or 3 is all you need - just go with that. You know yourself better than anybody on the internet could hope to.
But, please, don't use general "you" when referring to yourself, it's really confusing.
I had a line in my comment hoping to stave off stupid things like this. I suggest you go back and re-read the last paragraph, it's only a couple sentences long.
