Swaghauler, your answers to questions about shotguns have been great, very informative.
I'd like to add something about the SPAS-12 from personal experience - it's 0.5kg to 1kg (1.1lbs to 2.2lbs) heavier compared to all the other semi-auto shotguns I've ever seen and that extra weight feels like it's all sitting on your off hand.
For all the "cool" it might have for being Arnie's shotgun in The Terminator, it handles "big & heavy" -- A bit like Arnie I suppose haha
