The P90 is fun on auto but to plink with its ergonomics just don’t do it for me. It’s sight picture is difficult for me to get used to. It shoots fast and I do like the 5.7 round. But, it’s not an MP7. I’m not being funny all the women love the P90.
I think the 416 with a can in a full on zombie apocalypse is the way to go. Or a 417 for that matter. But there’s something to be said for real stealth, I haven’t found anything that can compare to the SD. In a brave new world I would take stealth over punch until it’s full on conflict. I have a G36C in 300Blk that is uber quiet and the Sig Rattler is up there too. But even subsonic 300Blk doesn’t match the SD. I just love that thing. Also, not sure about you guys but I have problems with 300Blk cycling sometimes. i do mainly shoot that crap FEDARMS put out several years ago. Still going through cases of that stuff. It sure was cheap.
