> Sword users can learn new techniques. Wizards can learn new spells. Characters can become visibly stronger, or to learn to wield stronger arcane forces. But a guy with a gun can... what? Get a bigger gun? A guy with a gun can learn skills for shooting better. He starts with Stormtrooper shooting skills, and ends like the Man with No Name. Watch an old spaghetti Western, and there are clear themes that the protagonists are far more skilled at firearms than most people in that world. I'm reminded of a scene in The Good, the Bad and the Ugly (I think) where the character Tuco escapes or something, goes to a frontier store to buy a gun, then disassembles all the guns at the store, quickly and carefully examines all the components, and reassembles all the best parts into the one he then steals, which shows his knowledge and skill. In those movies the characters' skills are taken as given, but I see no reason why you couldn't have a skill-building arc for them any less than for a swordfighter, a martial artist, or, a wizard.
