As promised, a short "review" of the the Franchi SPAS 15, basically just giving my first impressions of the shotgun.
Look: Indeed the SPAS 15 is a ugly weapon. It is bulky and heavy. Processing is rough, there are numerous weld seams noticeable.
Ergonomics: Compared to other shotguns the stock is quite long, but comfortable for me. Smaller shooters certainly will run into problems without modification. Safety (there are two) can easily manipulated with the trigger finger or the strong hand. The "pump" function" works, but it is only a band-aid solution...ergonomics really suck, because you have to grip very far to the front. But why use the pump function when you have a reliable self-loading function? Here you can see that it was designed having law enforcement/military in mind, when using less lethal ammo...
Magazine change is somewhere between AK/AR.
Function: I tested the SPAS with several different ammo brands I had at home. bird shot (three types, two light loads for trap and skeet, one hunting load), buckshot (#04, #01, #00), slugs (sporting (very light, mild load: Brenneke K.O., hunting: Federal Power Shok). The Franchi ate every round without a hiccup! Impressing. And it was fun to shoot.
Those you are searching a reliable self loading shotgun with a detachable magazine, go for it, if you can find one.
