I bought one of those Promag aftermarket magazines for the No.1 MkIII* Lee-Enfiled. It didn't seem to hold the rounds in place properly unless I fiddled with the stack in the mag a bit, after loading. Then, when I ran the bolt normally, I got a bunch of misfeeds. This was a while back so I don't remember the specifics.
Thanks to the pandemic, there was a pretty considerable gap between the time I bought and opened the packaging of the mag and the time I finally got to around to using it. As such, by the time I became aware that the mag wasn't working in my SMLE, the packaging was long gone - and I wasn't even 100% sure that I'd bought the right one; that is the one for my No1, versus the mag that Promag sells for the No4. I wanted to make sure I wasn't getting misfeeds because I was using the wrong version of the mag, so I went to my local gun store to compare my mag to the one's the store had, in unopened packages.
My friend who works at this store spent a lot of time opening up packages of both versions of L-E Promags he had in stock. Strangely, neither he or I could see any differences between the ones he had, marked No1 and No4 - and both of these seemed identical to the one I had bought earlier. Partly because my friend at the store had spent so much time looking into this situation, I decided that I should at least buy another Promag from him - which I knew, for sure this time, was the one packaged as a replacement for the No1 gun.
I tested this new one in my No1 and if had the same problems as the one I had bought earlier. I the tried the newly-bought one - and the one I bought previously - in a No4 and neither feed properly in that gun, either.
I now know why these aftermarket L-E mags by Promag are made with that distinctive pointy edge at the rear heel area. They may be crappy mags, but they might make really dandy doorstops.
