I’ve seen a handful of people claim that the lack of legs on the follower (that’s how they get the extra 2 rounds) can cause them to jam compared to 13 round mags, but I have yet to ever see it or read it from someone firsthand - it’s always “I had a friend…”.

I’ve never had an issue with them. MecGar is the OEM manufacturer for Hi Power mags, they just don’t sell the “rat trap” mags themselves.

Now I wish I’d picked up more 20 round MecGar mags when they were easier to find.
