Customer Reviews

Owner of one Review by JimmyC
Out of the case, looked great. And, at the range, looks quickly changed to ravaging targets. What it did was eat the center out of the target while ingesting steel cased ammo as well as fmj. I am quite pleased with the performance and looks. And it fits my hand comfortably. What is not to like? (Posted on 4/1/2016)
