    Fantastic design and feel, easy operation and smooth mechanics make this a fun system to use at the range or an excellent home defense tool when a full size weapon is out of arms reach.

    Took some getting used to inserting and removing gun but once you get the hang of it you wont have a better time shooting. Excellent quality, beautiful looks and MAN what a blast to shoot. Stuck a cheap red dot on and accuracy was spot on. Well worth the price
