That's funny, cuz with over 10 million sold, there must be a lot of unhappy 870 shooters out there.Do not buy a Remington 870. I cannot stress that enough.
From Wiki .......
Sales of the 870 have been steady. They reached two million guns by 1973 (ten times the number of Model 31 shotguns it replaced). As of 1983, the 870 held the record for best-selling shotgun in history with three million sold.[5] By 1996, spurred by sales of the basic "Express" models, which were added as a lower-cost alternative to the original Wingmaster line, sales topped seven million guns. On April 13, 2009, the ten millionth Model 870 was produced.
