    I've noticed that there is a difference in the amount of play in the forend of my two CZ pump guns.
    On my 12 gauge, with the forend in the foreward, closed, position, there is about an eighth of an inch of fore and aft play. But there is no play at all on the 28 gauge. What's the deal? Could there be that much of a variation in tolerances between to guns from the same factory?

    As long as the bolt is locked solidly into battery I wouldn't worry about it. They're not handfitted guns - there will be tolerance stacking caused by mass production. I have seen this on numerous 870 shotguns. You could drop a wood dowel down the bore and check if the bolt is moving any on the one with fore end play. If the bolt moves there is a problem.

    There is a notch in the barrel extension, which provides a finger joint to secure the barrel to the bolt. The tab of the bolt was not in the notch of the barrel, so there was exactly that much play in the slide; nearly a quarter of an inch. Problem seems to be now solved. Incidently, the people at CZ-USA seemed to think that that much play in the slide was acceptable and normal. Go figure.
