Seems like a good start, although I'm concerned that double barrel length = double damage/double throw could be a bit overkill.
I'm currently looking into GURPS Lite and how it suggests to model firearms (I still like the idea of only using d6 for everything).

On page 20. Seems like a pretty good start, and I think one can easily define some sort of modification table for certain calibers and barrel lengths and so on.
9 mm -> 2d6 base damage or something like that, other modifications allowing +2, x0.5, whatever sorts of modifiers.
Looking at the tables the amount of dice can become quite daunting though. Blaster rifle doing 12d6 damage? But that's subject to change, of course.
