I got the new 2.0 in 45 and they are black with a white or grayish stripe . I picked one up at a store and was 10 round solid black follower . I do not want to old mags .?????????????
As far as I know, there have been no problems reported with the .45 mags. The newest version has a square hole in the base plate where the original had a round hole. I don't know why they switched because it makes no difference to how it works.
Thanks ,my new MP9 mags have the square hole at the back and I looked at the new 2.0 45 gun and its round and the spring is blue . That white line looks like a fact check of some kind it just rubs off the follower .
