This is a beautiful piece of equipment. It is a 209 caliber. We do not sell the ammo due to the cost of shipping (hazard materials). The ammo can be purchased at any local sporting goods store that sells live ammo. The 209 is the primer used to load shot gun shells so it is readily available locally. This starter pistol using the 209 ammo is larger than the .22 caliber starter pistol so it gives a much louder sound when shot. This is a competitive starter blank gun and can not shoot live ammo or be altered to shoot live ammo.
