The STG met my expectations besides the charging handle operation not being exactly the same, as far as the receiver cut out. I was surprised that the mp43/1 muzzle nut IS REMOVABLE. I'm probably one of the only people who's silenced a gsg stg.
That said I'd love to have an mp40 but the quality and detail is going to really have to be above and beyond. In fact, why don't they just make it a pistol in 9mm? I don't think it would be subject to ammo restrictions then. Of course, that's not possible either. I understand that GSG mainly deals in high purity zinc and operates primarily as an airsoft manufacturer. Maybe some day, someone will carry the torch. Unless this thing is in the $300 range I can't see paying more than I did for my PPS-43 which is a true piece of history and a once-was full auto base gun converted to semi.
