I've had 2 of them, got rid of both, they are clunks compared to an 870. Honest the first thing you need to do is to run a couple of boxes of high brass loads thru it to see if it functions correctly and ejects easy. Go buy a couple of boxes of 3 3/4 de x 1 1/4 oz express type loads and shoot them on hand trap and doing doubles too. If some previous owner has cleaned the chamber without enlarging the chamber extension ring the same time you will have hard extraction because the hull has expanded out past the diameter of the chamber ext ring. Low brass doesn't allways show you this. You need to know if it's a RELIABLE shooter before you spend money on choke work. MB
