Almost any "safety" added points for calculating whether it could be imported under GCA 68 implementation rules. As did "target" features like "target grips". So odd things on any imported sidearm may have that points system as part of the design for the US market.
Don't know if this is the case for this pistol but lots of odd "features" at one time came from this stuff.
