I imagine if there had not been a Glock 18, there wouldn't be 33 round Glock mags. However, they just released a 24 round 9mm round mag, so who knows if they would have gotten around to it eventually.

A lot of folks like them for home defense and think they are practical in that role. A few guys keep them in the car or in bags when traveling for reloads. I own several just to have them, but don't usually keep them loaded except when there are incidents of civil unrest going on in my area.
