If I read this correctly then a stock PS90 can have the same discharge?Promoted Pawn said:about the drop safety.
it's not a firing pin block, it is more of a sear block,
It sits in the back of the trigger group and, when activated tilts forward and blocks the rearward travel of the "sear carriage", thus preventing the hammer from being released.
It is only activated by a muzzle-first impact.
A sharp blow to the butt of the weapon can still cause it to fire.
