I only have one pro to small of back and cross draw carry. Pro If this is the only way you can conceal your gun. That being said I do not even teach cross draw or small of back carry in my courses because it causes you to sweep your own body with the muzzle of your pistol. If at all possible I advise against it. I have seen and heard of people shooting themselves in the kidney or other parts of the body trying to re-holster or upon drawing there pistol. But if it is a last resort then it's better to carry than not to carry. I hope this helps and I in no way want to discourage you from it I just don't practice it or advise it to my students.
