Surprisingly disappointing - TROY HK Folding Tritium BattleSight

Excellent construction, very sturdy, HK style front sight is awesome. However. It is not spring loaded. It takes two hands to activate. One hand depresses the release button, which extremely stiff, and you need another hand to physically raise the sight. In addition the tritium part of the sight is small and wimpy. I expected much more for the price.
