When adding the Repeating Shot infusion (copied below from the Artificer Class page) to a pistol (not Exandria), the +1 attributes do not appear to take effect in the character sheet.
Repeating Shot
Item: A simple or martial weapon with the ammunition property (requires attunement)
This magic weapon grants a +1 bonus to attack and damage rolls made with it when it’s used to make a ranged attack, and it ignores the loading property if it has it.
If you load no ammunition in the weapon, it produces its own, automatically creating one piece of magic ammunition when you make a ranged attack with it. The ammunition created by the weapon vanishes the instant after it hits or misses a target.

You also need to attune to the weapon.
Helpful rewriter of Japanese->English translation and delver into software codebases (she/e/they)
Thanks, that wasn't very intuitive but it is working now!
