Gun Experiments: Converting a Glock 21 from .45 ACP to 9mm



(from Oct 2014)

This is the first in a series of experiments where I attempt to convert my Glock 21 into firing a variety of different calibers. From the factory the G21 is set up to shoot .45 ACP; in this video I will attempt to convert it into a 9mm Luger firearm. As far as I know, this has never been done before.

In the future I'm considering turning this Glock 21 into being able to shoot .40 S&W, 10mm, .460 Rowland, and even .50 GI.

For those who wonder why, I can only say -- for the hell of it. There's no truly legitimate, valid reason; it's more of a "just because I can" kind of thing. I've always been curious about these various conversions and how they'd actually work out, so ... I thought I'd just jump in and try it. The bonus is that it gives me another platform to test various ammo types from, and another barrel length.
