No, You Cannot Over-insert a Glock Magazine
While not a raging debate recently (although I have seen a few instances on various forums), I believe it is important to ensure gun fallacies are put to bed, permanently. Let me say it clearly: you cannot over-insert a magazine in a Glock handgun.
For example, many said that using a 17 magazine in a 19, or full-size in a compact gun, would have the magazine over-insert as the base plate was not there to stop over-insertion. While on its face, it makes sense, it shows a significant misunderstanding of the design of the Glock platform.
Every Glock magazine and frame have shelves built in to the left-hand side of the magazine and magazine well-respectively. The sole purpose of these shelves is to ensure that magazines cannot be over-inserted, in much the same way the Gen 3 PMAG has the shelf on the rear of the magazine.
It takes an incredible amount of force to bust through polymers that are loaded against one another vertically. By incredible, I mean more than anything a human could ever exert. As such, use longer Glock magazines anytime.
I carry a 17 magazine as a spare when carrying my 23 (converted to 9mm).
Don’t believe me, take it from some guys who do it for a living:

I would just like to acknowledge the respectable lack of sexual innuendo in this thread.
Such restraint, given the obvious opportunity, is admirable.
Penis.
Yes, you can. Keeping in the faith of the article, not all Glock 17 nor Glock 19 magazines have the over-insertion notch. Granted, those magazines will, in the case of the Glock 17, pre-date 1989, and in the case of the Glock 19 are limited to 1989 production only.
