And he calls himself a gunsmith? Don't let him work on any 1911's!
The passive firing pin block is there to prevent firing if the gun is doropped muzzle first onto a hard surface which could cause the firing pin to move forward under it's own inertia. Some people think it will prevent firing if the hammer accidently falls (which is physically impossible if the thumb safety is engaged and properly working). The only other way I know to make one fire is to pull the trigger which causes either series to go bang.
