A firearm sound suppressor cooling system comprising a sound suppressor housing with means for reducing the pressure of gases exiting from a discharged firearm with a shroud that is attached to the exterior of the sound suppressor housing, an annular chamber formed between the sound suppressor housing and the shroud, and a nozzle positioned at the distal end of the sound suppressor and the shroud. The nozzle produces a suction effect upon discharge of the firearm and due to the suction effect, ambient air is aspirated through the annular chamber, and cools the firearm sound suppressor.

1. A method of cooling a firearm sound suppressor comprising: a. attaching a firearm sound suppressor to the muzzle of a firearm, said firearm sound suppressor having a shroud surrounding the exterior of said firearm sound suppressor, and whereby an annular chamber is formed between said shroud and said firearm sound suppressor; andb. cooling said firearm sound suppressor upon discharge of said firearm through means for producing a suction effect by using the gases discharged from said firearm sound suppressor, whereby said suction effect aspirates ambient air through said annular chamber and along the length of said firearm sound suppressor, and wherein said means for producing a suction effect includes a nozzle positioned at the distal end of said firearm sound suppressor and said shroud. 2. A firearm sound suppressor comprising: a. a sound suppressor housing with means for reducing the pressure of gases exiting from a discharged firearm;b. a shroud that is attached to the exterior of said sound suppressor housing, whereby an annular chamber is formed between said sound suppressor housing and said shroud; andc. means for producing a suction effect upon the discharge of gases from said firearm sound suppressor whereby said suction effect aspirates ambient air through said annular chamber, whereby cooling said firearm sound suppressor, and wherein the means for producing a suction effect includes a nozzle positioned at the distal end of said firearm sound suppressor and said shroud. 3. A firearm sound suppressor comprising: a. a sound suppressor housing with means for reducing the pressure of gases exiting from a discharged firearm;b. a shroud that is attached to the exterior of said sound suppressor housing, whereby an annular chamber is formed between said sound suppressor housing and said shroud; andc. means for producing a suction effect upon the discharge of gases from said firearm sound suppressor whereby said suction effect aspirates ambient air through said annular chamber, thereby cooling said firearm sound suppressor and wherein the means comprises: a nozzle positioned at the distal end of said shroud;said nozzle positioned forward of the front end cap of said firearm sound suppressor; and an expansion chamber formed between said front end cap of said firearm sound suppressor, said nozzle and said shroud, wherein upon said discharge of said gases from said firearm sound suppressor into said expansion chamber and hence into said nozzle creates said suction effect, whereby cooling said firearm sound suppressor. 4. A firearm sound suppressor of claim 3, wherein said means further comprises: a. said front end cap of said firearm sound suppressor is a convergent nozzle, andb. said nozzle is a tubular nozzle having a convergent proximal surface. 5. A firearm sound suppressor of claim 3, wherein said means further comprises: a said front end cap of said firearm sound suppressor is a tubular nozzle, andb. said nozzle is a tubular nozzle having a series of angled holes, whereby said angled holes are angled towards the proximal end of said sound suppressor. 6. A firearm sound suppressor of claim 3, wherein said means further comprises: a. said front end cap of said firearm sound suppressor is a divergent nozzle, andb. said nozzle being a convergent-divergent coanda nozzle, said convergent-divergent coanda nozzle having at least one series of angled holes,whereby said angled holes are angled towards the proximal end of said sound suppressor. 7. A firearm sound suppressor of claim 3, wherein said means further comprises: a. said front end cap of said firearm sound suppressor is a tubular nozzle, andb. said nozzle being a divergent nozzle, said divergent nozzle having one or more series of angled holes, whereby said one or more series of angled holes are angled towards the proximal end of said sound suppressor. 8. A firearm sound suppressor of claim 3, wherein said shroud has vanes, flutes, circumferential bearing surfaces or shoulders on the internal surface of said shroud. 9. A firearm sound suppressor of claim 3, wherein said shroud has vanes or flutes and where said vanes or flutes have a helical, curvilinear or stepped curvilinear shape. 10. A firearm sound suppressor of claim 3, wherein said sound suppressor housing has vanes, flutes, circumferential bearing surfaces or shoulders on the external surface of said sound suppressor housing. 11. A firearm sound suppressor of claim 3, wherein said sound suppressor housing has vanes or flutes have a helical, curvilinear or stepped curvilinear shape. 12. A firearm sound suppressor of claim 3, wherein said front end cap of said sound suppressor has a plurality of holes, said holes positioned around the bore hole of said front end cap of said firearm sound suppressor, and whereby said plurality of holes vent gases from said firearm sound suppressor forward into said expansion chamber.
