Suppressed Government Model, MK II semi-auto .22 caliber target pistol. This unit is a no maintenance matte finished stainless steel pistol with stainless steel internal baffles. This will be the last of these as SWR will no longer manufacture this weapon due to the time required to manufacture them. This is the best suppressed .22 caliber pistol that I have run across. A very quite and very accurate weapon.
