Is there a List of archetypes and/or (prestige) classes that use firearm?

[Myth27]

Gunslinger (obviously)
Holy gun (paladin)
Trench fighter (fighter)
Spellslinger (wizard)
Siege Mage (wizard) "kind of"
....

Edit: I didn't specify pathfinder, can I change the title?

Check "classes/archetypes" and then search for "firearm."
