GSG/ATI MP40 - anyone have one?

[Wheelgun]

Just wondering if anyone has any experience with one of these? I’ve come across one locally that is used but seems to be in excellent condition. 10” barrel so I guess it is considered a pistol. It looks pretty cool and seems to be fairly well made. I’m interested in in hearing about reliability and if it’ll run cast well.

Thanks

Here’s a link to the ati site, for those unfamiliar with it.

Says that the frame is Zamak, run, don't walk away from that.
