It's been my experience that if you ever have to use your gun in self defense, even if no shots are fired, you find a way to make a larger gun work.

Having said that it's also been my experience that Glocks tend to be more compact and lighter than their S&W counterparts.

I don't see a noticable difference in weight and size between my Glock 26 and a M&P Shield. I also find the Glock to be more versatile (as is the 9C) because I can use any 9 mm double stack Glock magazine in it.
