The ZEV Technologies PRO Glock V2 Compensator you need will depend on what threads your barrel has. These ZEV Technologies PRO Glock V2 Compensators are all for 9mm but you will need the model that shares the same thread pattern as your barrel.
According to the manufacturer the ZEV Technologies PRO Glock V2 Compensator will work on any 9mm Glock as long as you have the proper corresponding threaded barrel.
If your Bear Creek Arms Glock 19 Barrel has threads that match the ZEV Technologies PRO Glock V2 Compensator, it will work. You need to know the Threads per Inch on your barrel not the rifling twist rate of the barrel.
