I replaced the synthetic furniture on my newer 870 to wood, came off a fellow TFL'er's 870. Easy, unscrew, screw, done. Well now im having "sticky extraction" issues. Is it possible to over tighten the nut or under tighten it? Its snug and tight with no play against the wood. Fire a shot, takes more pressure to extract, sometimes quite a bit more than others. Im confused as to what I did wrong.
