Yea, saw this yesterday. I still don’t trust it enough to put any real money behind it. It’s OK if you are waiting on a stamp though. I am looking at a Scorpion EVO again now. I think it’s a reasonable solution for a 9mm.
On short barrela I do not find stocks to be of any value for quick tactical shooting. A sling put in tension while pushing the gun forward is much more stable for that purpose. A stock is good for scopes but scopes are not that useful on short barrel short range guns.
