The system according to the invention provides wherein the quick coupling muzzle booster includes a booster slide with an external quick connect for coupling to the suppressor adaptor, and wherein the external quick connect of the booster slide includes a plurality of lugs corresponding to a proximal end of a housing of the suppressor coupling, and wherein the muzzle booster includes a booster piston that is coupled to a pistol. The system according to the invention may provide wherein the muzzle booster includes a booster piston nut with a spring, wherein the booster piston nut is coupled to the booster piston. ## Claims ### Claim 1 A quick coupling suppressor adaptor system, comprising: a quick coupling muzzle booster including a lock breech pistol coupling configured to be mounted on a lock breech pistol barrel; a direct rifle mount including a pistol caliber carbine coupling configured to be mounted to a pistol caliber carbine, each of the quick coupling muzzle booster and the direct rifle mount having an outer surface with a suppressor adaptor coupling; a suppressor adaptor having a suppressor adaptor outer surface including a suppressor coupling configured to be coupled to a suppressor and a suppressor adaptor inner surface with a complementary adaptor coupling to engage the suppressor adaptor coupling to selectively mount the suppressor adaptor to the quick coupling muzzle booster or the direct rifle mount. ### Claim 2 (depends on 1) The quick coupling suppressor adaptor system according to claim 1 wherein the quick coupling muzzle booster includes a booster slide with the suppressor adaptor coupling thereon comprising an external quick connect for coupling to the suppressor adaptor. ### Claim 3 (depends on 2) The quick coupling suppressor adaptor system according to claim 2 wherein the external quick connect of the booster slide includes a plurality of lugs corresponding to a proximal end of a housing of the suppressor coupling. ### Claim 4 (depends on 3) The quick coupling suppressor adaptor system according to claim 3 wherein the external quick connect of the booster slide includes three lugs corresponding to the proximal end of the housing. ### Claim 5 (depends on 3) The quick coupling suppressor adaptor system according to claim 3 wherein the muzzle booster includes a booster piston including the lock breech pistol coupling that is coupled to a pistol. ### Claim 6 (depends on 5) The quick coupling suppressor adaptor system according to claim 5 wherein the lock breech pistol coupling of the booster piston is threaded to the pistol. ### Claim 7 (depends on 5) The quick coupling suppressor adaptor system according to claim 5 wherein the muzzle booster includes a booster piston nut with a spring, wherein the booster piston nut is coupled to the booster piston, and wherein the muzzle booster acts as a linear inertia decoupler for a lock breech pistol. ### Claim 8 (depends on 7) The quick coupling suppressor adaptor system according to claim 7 wherein the booster piston nut is threaded to booster piston. ### Claim 9 (depends on 5) The quick coupling suppressor adaptor system according to claim 5 wherein the suppressor adaptor coupling includes a plurality of lugs. ### Claim 10 (depends on 9) The quick coupling suppressor adaptor system according to claim 9 wherein the suppressor adaptor coupling is formed as a three lug J-lug adaptor. ### Claim 11 (depends on 5) The quick coupling suppressor adaptor system according to claim 5 wherein the suppressor adaptor coupling of the direct rifle mount includes an exterior surface on one end matching the configuration of the exterior of the external quick connect of the booster slide. ### Claim 12 (depends on 5) The quick coupling suppressor adaptor system according to claim 5 wherein the suppressor adaptor coupling of the direct rifle mount includes a plurality of lugs corresponding to a proximal end of the suppressor adaptor. ### Claim 13 (depends on 5) The quick coupling suppressor adaptor system according to claim 5 wherein the direct rifle mount includes an interior surface matching the configuration of an interior of the booster piston. ### Claim 14 (depends on 5) The quick coupling suppressor adaptor system according to claim 5 wherein the direct rifle mount includes integral muzzle brake. ### Claim 15 A suppressor system comprising: a suppressor; and a quick coupling suppressor adaptor system, the adaptor system having a quick coupling muzzle booster including a lock breech pistol coupling configured to be mounted on a lock breech pistol barrel; a direct rifle mount including a pistol caliber carbine coupling configured to be mounted to a pistol caliber carbine, each of the quick coupling muzzle booster and the direct rifle mount having an outer surface with a suppressor adaptor coupling; a suppressor adaptor having a suppressor adaptor outer surface including a suppressor coupling configured to be coupled to a suppressor and a suppressor adaptor inner surface with a complementary adaptor coupling to engage the suppressor adaptor coupling to selectively mount the suppressor adaptor to the quick coupling muzzle booster or the direct rifle mount. ### Claim 16 (depends on 15) The suppressor system according to claim 15 wherein the quick coupling muzzle booster includes a booster slide with the suppressor adaptor coupling thereon comprising an external quick connect for coupling to the suppressor adaptor. ### Claim 17 (depends on 16) The suppressor system according to claim 16 wherein the muzzle booster includes a booster piston including the lock breech pistol coupling that is coupled to a pistol. ### Claim 18 (depends on 17) The suppressor system according to claim 17 wherein the muzzle booster includes a booster piston nut with a spring, wherein the booster piston nut is coupled to the booster piston, and wherein the muzzle booster acts as a linear inertia decoupler for a lock breech pistol. ### Claim 19 (depends on 18) The suppressor system according to claim 18 wherein the suppressor adaptor coupling of the direct rifle mount includes an exterior surface on one end matching the configuration of the exterior of the external quick connect of the booster slide. ### Claim 20 (depends on 19) The suppressor system according to claim 19 wherein the direct rifle mount includes an integral muzzle brake.
