@ Fall and Philip... it is possible to engineer a B&T style super speed magazine loader for a glock or Single load magazine, however it requires thinking outside of the box. Not only would you have to redesign the loader, but you would need to create a
uniquely designed magazine modified specifically to work with the loader. This is easier then it sounds, I came up with the following designs on my Note 5 in 10 minutes and I'm not even an engineer (probably should have been).
I'm new to this, so I don't know how to post pics, but you can check out my designs by downloading the pdf file I uploaded to my Dropbox from this link:
