9mm P Grand Power K100 Target Pistol

The K100 is equipped with a firing pin block drop safety. Not until the trigger is pulled does the firing pin block disengage and allow the firing pin to be driven forward by the hammer and strike the primer. The purpose of the design, according to many, is to keep the firing pin from being driven forward if the gun is dropped on the muzzle or the hammer, which has caused unintentional discharges on some pistols without the feature.
