The complete package, with the suppressor attached, weighs less than 25 ounces. It has an overall length of just under 12 inches. The sound of the bullet impacting the target is much louder than the report of the actual weapon itself.
The suppressor has no internal baffles - only tuned chambers. When the bullet passes each chamber, it causes the pressure waves to start cancelling each other and modulating the pressure levels and sound wavelengths. It is a tuned chamber suppressor design VS a baffled suppressor design(the most common). This allows it to be only .98" thick, by 5.7" long and weigh 3.3 ounces.
