Not harder but they may leave excess lead fouling in the barrel if you are not a diligent cleaner. Non-plated rounds may also be prone to feeding issues in a semi-auto pistol...many .22lr chambered semis are extremely ammo finickyAre "non-plated" rounds harder on a semi auto handgun then plated rounds?
