Phil of Clearwater Airsoft decides to treat his airsoft Glocks like a set of building blocks to see what happens when you mix and match parts. He starts by weighing the G17 and G45, noting that one carries a bit more mass than the other. The weight of the magazines seems to vary based on how much gas is currently inside, adding a minor variable to his initial measurements.

The experiment moves into the assembly phase as he swaps the slides between the two models. While the G17 slide sits on the G45 frame, the creator finds the visual result rather unpleasant. The opposite configuration proves even more difficult, resulting in a mechanical mismatch where the slide refuses to lock back, effectively ending the brief parts-swapping program.

Concerned that the inventor of the platform (Gaston Glock) might be turning in his grave, Phil restores both items to their factory settings. He finishes his demonstration by advising against these modifications and asks for a few more subscribers to help him reach a year-end milestone. With the equipment back in one piece, he concludes that keeping the original parts together is the sensible choice for his collection.
