Don’t get me wrong I am not saying pumps are useless all I am saying is they are misrepresented when people offer them as the end all solution to untrained (likely to remain that way) individuals for self defense which will likely be the most stressful event in a persons life increasing the chances of failure.Occasionally short-stroking is why I sold my 870. I replaced it with a Mossberg 930SPX, and never looked back. But that 870 Wingmaster, from 1972, was a great gun.
With high brass there are MANY reliable semi auto options. Not to mention reduced recoil.
