Haven’t used the Q. But I have plenty time with both the 22 TD and Mask HD. Personally, I cannot tell a difference on any platform, rifle or pistol, in terms of suppression. They are both “you only hear the action” quiet. They are also both noticeably quieter than my Sparrow, spectre ii and the Warlock I’ve used.
I hate to play favorites, but the TBAC 22TD is my personal go-to simply bc of the form factor. It fits in the blackdog/tacsol Ruger MK holster without modification and looks bad a&& on the VQ summit. The OD is almost identical to the summit barrel. I’ve used both on the Summit, Scorpion, and my VQ’d out MKIV Tactical. The MKIV has claimed many a squirrel, coon, oppossum, and rabbit in the last year, primarily, with the TBAC bc of the holster. It’s the Summit’s turn this year.
On the other hand the Mask HD comes wrapped like a cigar which is a nice touch.
The Mask is slightly shorter at 5.1” but wider and heavier at 6.6oz. The TBAC is 5.6” and 5.9oz according to their websites. Again, I can tell you, for myself, being able to fit the TBAC in the tacsol holster is a major plus. Neither suppressor negatively effects accuracy at all, in my experience. You won’t go wrong either way.
Heres the MKIV with the TBAC over a few corn stealers. And a side by side of the MKIV with the Sparrow (similar size to the Mask) and Scorpion with the TBAC
