Steel 870 Shotguns - Availability or Upgrades

[Moosh89]

Hey,

I currently have a PPS M870 Green Gas shotgun for my Aliens Pulse Rifle build. I like it because of the look (the ejector especially). I also prefer the "Gas in Shell" loading.

EDIT Once again, I'm convinced after multiple messages that upgrading what I have currently is more hassle than finding something "off the shelf". Thanks to those who have reached out, respectfully.

I'd like to find a steel 870, mostly for added weight like the Dominator DM870. The only thing I really dislike about the Dominator is the squared off ejector.

My Googling tells me that the Dominator is the only steel Airsoft 870 available.

I don't suppose there's any other steel airsoft 870s in development, is there?.
