EDIT (4-22-10): I've finally dug this thread up, and added a bit.
Specifically, I've added PH3-style
Superior Implement options for "guns-as-implements". No weight is listed because theoretically
any "gun" (read: crossbow, mechanically) can be found in any of these "superior implement" forms. The Price, then, is merely added to the normal weapon cost.
Superior Implement bonuses
only apply when using the item as an implement, with an Implement power - they have no effect when using the "gun" as a normal weapon.
-----------------------------------------------------------------------
While dabbling with the new double-weapon rules, I decided to try my hand an a gunblade. Doing research for it took me to the Final Fantasy wikia, which then lead me all over, and made me decide to better codify my existing "firearms" rules.
-----------------------------------------------------------------------
"Firearm" Weapons
For "firearms," I will use plain ol' crossbow stats. Essentially then, "guns" are just refluffed crossbows, which actually works out pretty well. To make them a
bit more distinct, I have a few feat options that players can select. The idea with these is that, while "guns" are easy to pick up and use (simple ranged weapons), it takes a bit of training to eke out their full potential.
Arcane Firearm Channelling
Prerequisites: Any arcane class
Benefit: You can use crossbows as implements with any arcane class. You do not gain the weapon's proficiency bonus to attack rolls when using a crossbow as an implement.
Deadly Firearm
Benefit: You treat all crossbows as high crit weapons.
[Note: I wonder if this one shouldn't be bumped up to Paragon, like Deadly Axe. The Drow racial feat that gives High Crit to hand crossbows is what makes me want to keep it here.]Scatter Shot
Prerequisites: 11th level, Dex 15, Con 17
Benefit: If you miss with a ranged attack with a crossbow and you wouldn't otherwise still deal damage on the miss, you deal damage to your original target equal to your Constitution modifier. This damage receives no modifiers or other benefits you normally gain to weapon damage.
[Note: Instead of having 'blunderbuss' weapons on their own, I just went the easy route, since the "damage on a miss" quality fits them well in the first place. Con as the requisite stat is representative of, say, being able to better control the kick-back of the weapon - better control, more miss damage. That's the theory anyways. Con also makes the feat mesh well with the Careful Shooter feat, and with Dwarves as a race.]The only "unique" weapon I've statted out thus far is the "gunblade" (or, in D&D terms, the Crossbow Sword). No other "guns" really require new stats.
Double WeaponCrossbow Sword +3 1d10 ----- 40 gp 10 lb. Heavy blade Stout
- Secondary End +2 1d6 10/20 ----- ----- Crossbow Off-hand, load free
[Note: As was pointed out in the prior thread, very few characters will actually take this weapon, or be able to truly benefit from it. Ranged and two-weapon rangers would both be better served with other superior weapons. Rogues would get no benefit from the heavy blade end. Heavy blade fighters are the best bet, though beastmaster rangers could also benefit (if they select ranged ranger powers as well). The heavy blade fighter is my favorite option; he can multiclass to glean some significant benefit from the secondary end. Ranger gives him some skirmishing options, if he picks ranged powers. Rogue gives him a 1/round sneak attack, which he can trigger with the secondary end, as well as the skirmishing options. To "sweeten the deal," I've also put together a Weapon Mastery multiclass option for the weapon, below. This note? Waaaay too long. 
]-----------------------------------------------------------------------
"Weapon Mastery" Options
The following two multiclass-only options are designed along the same lines as the Weapon Mastery multiclass options from Dragon, and follow those same rules. The first gives a more distinct fighting style for the gunblade user, though it remains most likely in the hands of a heavy-blade fighter. The second expands upon the "gun as an implement" concept, giving a character who wants to go that direction a bit more of a distinction - it's inspired by the "magic guns" of FF:Tactics, and the "gunner" classes of FF:TacticsAdvanced (mostly 2, as I sadly cannot find 1).

At 25th level, 3[W] + Strength modifier damage.
Special: When you choose this power, choose whether you use Strength or Dexterity to make the primary and tertiary attacks.
[Notes: I think everything is pretty fair for this one, though I'm a bit concerned about the potential for three attacks with the daily at level 25+. Granted, you only get each if the prior one hit, but still, it's like a slightly changed Blade Cascade. *shrugs*]-----------------------------------------------------------------------

[Note: Not "guns" related, but FF related, which is enough. Mostly an attempt to "run with it" on the "weapon mastery" style classes. It's not limited to martial-only, which I like. I could see several classes multiclassing Dragoon, and all having very different approaches to it: Barbarian, Cleric, Fighter, Paladin, Warden, Warlord - each could be very effective with this, and bring something unique to the concept. Beastmaster rangers might also be able to pull it off (and probably something I'm missing).]-----------------------------------------------------------------------

(*: Personally I'd call it a Mythril gun - but Mythril is a weapon enchantment, so it's not totally correct.) Rules for Superior Implements (including property explanations) can be found in PH3, page 195.

ClosingAny feedback is greatly appreciated. I know it looks like a bit to sift through (and a
bit like madness, to boot), but any help would be great. And even if you can't (or don't care to) provide feedback, enjoy!
But thank you. The gunblade itself, and the MC-only option for it were both kind of "Why the hell not?" moments originally, but now that they're done... it really makes me want to play a gunblade-specialist Fighter.
