What variant do you got? Whatever it is, just stick with it. Focus on your P30 for the next six months and leave all your other guns in the safe. Also try a different set of grip panels every time you take it out until you find a setup that works. Most people (including myself) find that the medium is the most comfortable, but I'm a lot better shot when I use the large sides and backstrap. Picking up a set of Heinie Straight Eights is a wise investment too.
