I have several model 12’s and more 870’s.. The 870’s just shoot.. Thousands and thousands of rounds.. I think it has been in production far longer than the model 12.. My heavy duck, is a great shooter, but it has had problems functioning.. I took it to a top gunsmith and he corrected the problem.. But he told me the 12 has more moving parts and therefore harder to keep everything in tune.. As much as I love my old pumps, the 870’s would be the last to go.. I have never seen a model 12 shoot rings around any 870...
