I'm not talking about .45's, revolvers, or any other calibers here. If you had to pick only one 9mm, what would you choose and why? For me it would be an easy choice: my Walther PPQ. I've owned several other 9mm's and I still have a few, but the PPQ is easily my favorite. I love the size, weight, action, ergonomics, accuracy, features, looks, and reliability. I'm curious to hear what you guys have that you simply couldn't part with or what you'd really like to own.
