If I want to use the 5.7x28 round I just use this.
At present this is one of my walking around the place at night guns.
I like the pistol but the PS 90 doesn't appeal to me.
And as a comparison between the FN PS 90 and a shotgun.
A full load in the FN PS 90 is 50 rounds of 22cal size bullets.
Just two #4 S&B Buckshot shells have 54 22 cal size "bullets".
And you still have 135 "bullets" left (7 shot shotgun).
The 5.7x28 armor piercing round isn't available to civilians.
EOTech or similar sights can be mounted on shotguns, if necessary.
"You defend that shotgun all day I know, your probably have one and you have a ton of experience with carbines eh?"
Matter of fact I do have a ton of experience with Carbines and I still say that there's almost nothing as deadly at HD range as a shotgun loaded with #4 or 00 Buckshot or slugs.
Bushmaster M4 Carbine.
45 ACP Marlin Camp Carbine.
M1 and M2 Carbines.
UZI Carbine.
45 ACP Thompson Carbine.
M2 Carbine.
And even experience with things that are close to Carbines.

I would get something that works BETTER for IN HOME defense.
I think you should get whatever works better for you.
Even though I believe the SG is the most devastating HD gun, it isn't my first choice because of my particular HD needs.
