I shot them in the Army. Supermatic Citation 107 Military, IIRC. More accurate than any of us could shoot.
Never cared for the thumbrest stocks nor the "toe" mag release.
Actually have one that's been sitting in my office for months. Belongs to a "friend of a friend". Was dropped off for my consideration. Made an offer that he did not accept, but the guy seems to have disappeared. So here they sit.
Beginning to wonder if there's an "adverse possession" rule that applies to guns!
