I have the OR3Gun components in my 935 and it does birdshot fine.I ran across a 935 used that had a choat barrel extention and the barrel cut to about 20", just what I was looking for. I test fired it with oo buck and bird shot, both 2 3/4. It would not cycle the bird shot so I ordered the part from or3gun we will see what it gets here. More plesant to shoot than my 590.
