Shotguns are excellent home defense weapons, and honestly are a bunch of fun to shoot. I have a clay pigeon thrower at my mom's farm (where I keep my shotgun) and it's a blast.
The Spas 12 isn't exactly a practical choice in 2024 compared to other shotguns on the market. Still definitely a cool one though for anyone who likes any of the number of games and movies that featured it heavily like Jurassic Park or Half Life.
The cost of a Spas 12 is astronomical compared to other new production tactical semi automatic shotguns. You can get a Mossberg 940 tac for around a grand. A Spas 12 will probably set you back more like four grand.
It's definitely a cool gun, but not something I'd recommend someone go to for practical purposes. Others just do the same, or more, for less.
The shotgun is the most versatile gun someone can buy. By changing the shells used in the gun, you can completely change its usage. You can even get interchangeable barrels for different uses, and most shotguns have interchangeable chokes to change the distance and pattern. Shotguns are awesome.
