worked great on my 457 magazine! After some loading and unloading, the spring got to the point where the extra 3 rounds were easy to load up while still feeding good.

I ordered two of these. Both fit very sloppy. One works OK, meaning I can usually get 12 rounds loaded without too much trouble but 13 rounds is difficult. The second one rarely if every works. The magazines both load perfectly normal up to 10 rounds. I bought these because I thought the fact that they are aluminum vs plastic would be better. I was wrong.
My anarchy outdoors plus 3 extension is plastic but flawless.
