Finger Guns weapon properties

 Hello, been playing a Gunslinger; Spellslinger in a current Campaign  and had a Question that stumped the GM as well. 

We know that the Finger Guns have the 'Slow' Property but does it have any others? As it has no weight it could in theory have at least the Light property. Which would mean it could be used for a Bonus Action Attack in conjunction with another Gun attack.

 If it doesn't say it has another property, it doesn't have another property.

Seems like an oversight as there few firearms that actually DO have the 'Light' property, in fact only one I found was the Submachinegun which shouldn't have it...

There's also the Exandrian Palm Pistol from Critical Role's Gunslinger. The Light property makes it compatible with CR's Firearm Specialist feat, but may also go with what you're looking for. 

But Anathar is right that spells only do what they say they do. Finger Guns have the Slow Weapon Mastery but no other properties unless otherwise listed.

Worth bearing in mind as well that each weapon only has a single weapon mastery so if it's got Slow then that's the one the decided to go with
