There are many good pump guns. I own 4 870's, 1 590, and a BPS. I'll admit the 590 has a bayonet lug and the BPS is a 10ga, so they don't see nearly the number of shells the 870's do, as I use the 870's for things that require far more rounds. Of the 4 870's, I've spilled many rounds through them for hunting and competitive uses. I know that I've yet to have a malfunction through any of the 870's, with around 25 thousand rounds. The 590 has had safety problems with heavy loads, and the BPS has it's BPS problems. I can't tell you why the BPS sometimes fails to feed other than it occasionaly leaves a loaded round on the ground that should be in the chamber. It could be my mistake, but it seems they all should work the same, and I've shot MANY rounds of skeet, and quite a few game birds and fowl with the 870's without a single malfunction. My vote goes to the 870 as the most reliable of those I own, which cover the 12,16,20,28 guage spectrum. The 870 has never cost me a shot at anything, I cannot say the same for the 590 and the BPS..good guns that they are.
