Not sure I'm a fan of it only fitting one type of Glock though....kinda cool concept.

At 2:53 he shows the DB without suppressor, but he does not show what ammo he uses...and he shows the subsonic DB but does not say if it is with or without suppressor... then he shoes supersonic ammo DB but does not say if it is with or without suppressor. We can't measure any improvement at all since there is not consistent measure. Best case assuming subsonic with a suppressor, 144.9 with a suppressor is not all that quiet for a can. Maybe a heavier spring in the gun to delay the blowback a millisecond and have less gas escape would help but he needs to test it, not leave it up to us to figure out. Good design, poor implementation.
Fool-proofing serves only one purpose: identify bigger fools.
......very Maxim Niney. Very neat concept.
