Paul,

I shot the Optimus Micro, alongside my Dead Air Mask and TI Quest.

I used my Ruger Mk 4, with a Tactical Solutions barrel.

Optimus Micro; 9.55 oz 1.22"D X 5.375"L

Dead Air Mask; 8.35 oz 1.07"D X 5.125"L

TI Quest; 7.4 oz 1.0"D X 5.0"L


I ran two magazines of CCI Mini Mag's through the Optimus & the Mask (without hearing protection).

I could not tell any difference between the Dead Air Mask and the Optimus Micro in suppression. Both are quiet enough to be hearing safe.

The TI Quest was loud enough that I quit after three rounds, and shot the rest through the Optimus Micro.

There's less difference in the weight of the Mask and the Optimus than I thought==> only 1.2 ounces.
