I have always been a Glock guy, but recently gave my 19 to my wife and bought a TSW 4003. Its a nice gun, but I find myself missing my Glock. I am wondering if I should go with a 17 or 22 with 9mm barrel. I've had quite a few 9mm, but liked the .40 when I shot it. Anyone have any suggestions on 9 vs 40? Maybe pros and cons? Looking to get one in the next couple weeks if anyone is going to be getting rid of one. Thanks
