yes, but the chance of misfire is for the gun. You use it more, you misfire moreThe gun doesn't get 4 iterative attacks. The user does.
yes, because the chance of misfire is tied to the gun, not their skill levelA PF1e gunslinger who is supremely skilled (level 16+) makes four attacks per Full Attack, because they are extremely skilled with gunslinging.
As a result of this thing--arising out of their skill with gunslinging--they now encounter dozens of misfires every day. They are in no way even slightly better at preventing misfire than they were when they first trained to use a gun.
Same as rolling a 1 on a d20, the more often you roll, the more often it will come up, even though you get more skilled with your sword or whatever
