"Forgotten Weapons" Take on the SPAS 12
If you're not familiar with the "Forgotten Weapons" channel on Full30.com and Youtube, you should be. Ian does some really good reviews of some amazing firearms that most wouldn't otherwise get to see. His video on the Pancor Jackhammer is worth a subscription alone. In this video he takes on the SPAS 12, and while that particular shotgun looks to need a little TLC I think he does a great job summing up the features and some of the quirks in a concise manner.
