Jihad?
Its a nice gun, but so is Glock and others. I'd just choose one you feel you like and stick with it and train it a bunch. If you're looking for a concealed carry it is a full size frame and slide but otherwise quite nice.
For me the question is not “do I need another gun” or “do I need a particular gun” but rather “when am I going to get my next gun.”
