Abstract:
First round shot noise and flash caused by combustion of oxygen contained in the air residing in a firearm sound suppresser can be reduced by providing a valve that communicates with the baffled interior space of the suppressor, and connecting a source of non-flammable gas such as CO 2  to the valve in order to inject the gas into the suppressor. The non-flammable gas displaces the air in the suppressor, removing the oxygen available for combustion when the first shot is fired.

Claim (Index 4):
The apparatus of  claim 3  for use with a pre-existing gas source, wherein said valve further comprises:\n a valve first end configured to connect to a pre-existing source of compressed gas; and \n a valve second end communicating with said baffled interior space,\n wherein said valve is configured to allow passage of gas from said valve first end into said baffled interior space via said valve second end when a source of compressed gas is connected to said valve first end, and acts to block passage of gases therethrough when no source of compressed gas is connected to said valve first end, such that the user engaging the source of compressed gas with the valve first end acts to open said valve.
