[suum cuique]

What kind of mag is this:
It came with my shooter, it's an aftermarket mag with a plastic follower and a plastic bottom. I shot already 500-600 rounds with my Luger and it works great. I had maybe 3-4 times a problem with the last round in the mag standing upright.
I thought maybe it is a Cheaper-than-dirt mag, but those magazines are not reliable, as far I know. This one works great.
