None of the firearms listed in the 2024 DMG have the martial tag applied in their item listing. This is causing those firearms to be unavailable for the 2024 Artificer repeating shot infusion/plan. I believe it also causing them to be ignored by the archery fighting style, at least when acquired via the fighting initiate feat. This can be seen on the sheet listed below.
