yep what he saiddont put too much stock into that test - it was only firing 3000 rounds of buckshot.
id hand you any one of my pumps and bet that they would pass that easily.
Remington did not submit the 870 because the test required an ambidextrous safety and they did not want to redesign/retool for a run of <50k shotguns which represented a couple months of sales for them. they already owned the civilian and police markets and had a lot more to lose if they 'failed' the test due to some nonsense such as the ergonomics of the safety or an unlucky one in ten-thousand failure. Mossberg would have sevrely damaged their reputation by touting that the 870 had 'FAILED' the milspec test.
also, price is the bottom line for many decisions the military makes and the Mossberg with its extruded aluminum receiver and stamped/cast parts was a much cheaper shotgun to build - so even if Remington had submitted the 870 and also passed the test, it would most likely have lost the contract to the cheaper gun anyway. so they had very little to win, and a lot to lose.
Or.....the Mossberg is just a better all around platform, and Remington knew that, and didn't step into the ring!
Highly doubt it.
i keep hearing the ambi safety argument.
i understand that lefties are handicapped, and i sympathise, but wtf? they cant reach the other side of the triggerguard with their thumb? how do you think righties actuate the safety? if you cant 'adapt' to do such a simple thing, then natural selection should have its way with you.
the only real world advantage i see in the Mossberg is the shell lifter that stays out of the way for easy loading. if im out shooting my 870s for several hours my thumb gets raw from the damned lifter.
but the 870 has its own advantages -- like easy addition of mag extensions, steel receiver for more robust sight/rail mounting and parkerizing (i believe the durability argument for steel/aluminum is moot), and a better aftermarket.
all in all i prefer the 870s, but if i woke up one morning and all my 870s were replaced with Mossberg 590s, i wouldnt cry about it.
