PCC for home defense?

I have some older friends—early 70s but both very fit—who want a gun for home defense. They have a Glock 48 for taking on walks at night but want something they can both shoot comfortably for home defense. It’s a good size house; long sight lines inside; neighbors not in danger of over penetration.

Would a CZ Scorpion, SIG MPX, or CMMG Banshee be good options? I’ve not shot a Scorpion or MPX, but my buddy’s Banshee is sooooooo easy to shoot accurately. What does the hive think?

Remember, this is for home defense, not a Gucci gun or high end competition gun.

I crossed posted this in the CZ sub for anyone thinking they’ve seen it twice.

Thanks!
