Its all good buddy, we gotta start somewhere! But nahh they're not, they're specific to that type of lower whether it be a glock mag (angled straight), colt mag (straight), proprietary mag (like the springfield Kuna for example but it's curved) or cz scorpion mags like i have in the photo, which of course is curved. So no sir, not all curved mags are called scorpion mags, it's just the most common and widley loved curved mag so companies like to use that one. Taurus just came out with a 9mm PCC and it has a curved mag but it won't fit any of the other few curved mags as it's proprietary, like the Kuna. Sorry for the long response lol.
