It filled the same niche as the TEC-9, but was fed by S&W 59 series pistol magazines in the grip, had decent adjustable sights, wood furniture, and a flash hider IIRC.
My local dealer had a very nice one for $450 a year ago. Despite having a supply of hi-cap S&W magazines on hand, I never even thought of buying it, it would be OK as a dedicated car gun, but I don't keep a weapon in the car unless it is on my body.
