The quiet choice:
The veterinary pistol SIX is a very unique manually operated bolt action pistol. The manual operation, ported barrel and integrated suppressor make it probably the quietest pistol in the world.
B&T developed the SIX in response to requests from Swiss veterinarians that required a very quiet firearm for dispatching sick cattle or game injured along the motorway without disturbing the other animals or residence in the area. The development goal was to have quietest possible sound but with sufficient energy to dispatch a large bovine animals quickly with a low risk of ricochet or over penetration. The sound produced by the SIX is less than 125 dB. Supersonic ammunition can be used and will have the velocity reduced to subsonic speed by means of a ported barrel.
