I've had surprisingly good results using a grease-charged 9mm micro-suppressor on my CZ 452. Wouldn't have thought it would work well at all, due to the oversizing of the baffle holes allowing too much space (& therefore blast) around the bullet as it passes thru them, but it does quite well. Much quieter than my gamo pellet rifle.
Actually, the remington subsonics as you used in that video are what I most use in mine as well.
{edit - duh... Didn't mention - the suppressor is an AWC abraxas titanium; a 9mm suppressor that's about the size of a typical .22 suppressor. This is it in the middle, between a TAC-65 and AAC Pilot .22 suppressors. Very small for a centerfire unit:
