If you had to choose between all the guns you own as your favorite piece, which one would it be, and why?

Since this is such a tough question, I'm going to have to wait a bit to see some other answers before I come up with something.

Could be sentimental reasons, accuracy, beauty, ruggedness, dependability, etc. So lets hear it!

And if you have a picture of your favorite gun, make sure to post it up when you give your reasons why its your favorite!
