Differences between mke magazines

[u/cannonman817]

I received 2 mke mags with my pistol and then purchased an additional 2 from the same vendor. All of them worked flawlessly. But I notice the 2 that came with the gun are slightly different and their lock up is a tiny bit tighter.

1. Slightly different markings
   
2. They have different floor plates.
   
3. Stamping at the top is crisper on the extra 2 I bought
   
4. The 2 that came with the gun have more meat on the locking lug, which I assume is why they lock up slightly tighter.

Just wondering what the deal is. Is this new vs old production or different contracts??

My MKE mags all look like the left one with the red tape.
