Must be hard making mags for a type of gun thats been around the 60’s - Elite Tactical Systems Heckler & Koch MP5 9mm 10-Round Pistol Magazine

Ordered 3 of these on sale, price was low enough to take the risk.

I have 2 MKE AP5s, and not even one of the 3 mags I got fit them. And I mean at all! I had to file each one, front and back in 2 areas to get them to even consider going into the mag well. I’d bet I have 2 hours of fitting in the 3 mags. And they are still a little tight .
I have not had the chance to test fire using them , but the amount of fitting required alone warrants this review.
I will likely never buy anything made by ETS again.
