It also explicitly says "turn it into your arcane firearm", which implies it is no longer a wand/staff/rod and is now something different. It also refers to "the firearm" (no arcane) when casting spells through it. If it is still only a wand/staff/rod, why would it be "turned" into something different? The description is definitely NOT clear on this. Sage Advice is silent on this, and it must have come up before; which leaves it open to interpretation. For myself, I interpret the word firearm to mean firearm.
