Picked up this Black Aces Semi Auto Pro Mini 12 ga this morning. With all the rain, unable to run a test firing. My Range looks like the Mekong Delta. Has a 10" barrel. 2 3/4 or 3" shells, Holds 3 + 1 rounds. Anyone else had a chance to fire one yet? You Tube videos show promise. Placed my SUV keys in picture to show compact size of the 12.. Will update results after 50 or so rounds..
