Ok, not great - Springfield Armory 1911 9mm 9 Round Magazine

I got two mags, both worked after leaving them loaded overnight. However, after a couple loading and unloading cycles, I noticed one of them fails to lock open the slide when empty. I’m only giving 3 stars because for the price, I’d expect them to work exactly the same as the factory mag that came with my Ronin. I’ve had no issues so far with any other brands, but these two are strictly for range use after the first 200 rounds.
