It looks like Ruger got smart with this 9mm carbine. The You Tube video I saw stated the trigger was at 4 lbs. and not the normal lawyer proof trigger that ruger has been known to use in the past on some guns. Also the two targets shown were very good 50 yard groups and the only fail to eject was one of the blazer ammo rounds that can give problems in other guns.
I plan to pick up one as the model without the threaded barrel is approved for CA. sales. I expect Ruger to later chamber it for 45 acp and 40 S&W. Coming out in 9mm was a good move as non reloading buyers will get it knowing they can get ammo for it at a cheaper price then 45 or 40 cal.
