I know you can duplicate it with 9mm+p+ and also have more capacity. Heck I watched a video from Australia where a guy had a pump ar in 308. Now I’m kinda wanting one of those.
It’s just a want thing.

I built a vf500f racebike back in the day because "I wanted to" so I get it.
sounds doable.
get a Glock mag lower for .40sw, build an upper with a 9mm barrel, have a gunsmith ream it for 357sig, enjoy your unicorn.
my unicorn has been in a storage unit for 23 years, I get it.
this is America, all you need to say is "because I want to and it's my money"
just post pics and results for the rest of us to enjoy...
