What kind of Gun is on the Cover of "Spies Lie & Spies Die?"

I had to decide what kind of gun to use on the cover. I knew I wanted it to be golden and hang on the ribbon but should it be a Smith and Wesson? Maybe it should be Remington or maybe it should be a Barretta. All three of these guns appear in the nine stories of "Spies Lie & Spies Die." I decided on the Berretta because there are more Barrettes in the book.  I looked at one and using my mouse I clicked off the image of the gun in Photoshop. I added in the shadows and details. (Although I purposefully kept it a bit nondescript on the details.) Then I flipped it upside down onto the ribbon.
