Yours may not, but it’s not unknown among new or old 870s. Look for “fix 870 jam” videos on Youtube and you’ll see what the problem is.
As for the short stroke issue, it does affect even the experienced and strong. Here’s hickok45, a famous YouTube shooter and gun reviewer comparing pump and autoloading shotguns and even *he* shortstrokes the pump.

He unintentionally demonstrates the first major problem with pump shotguns in under the first minute of the video - the required user interface. Specifically, first he demonstrates failure to pump and then he short strokes it immediately after in the rush to catch up to his shooting pace, the classic problem with a pump gun. This isn’t even under serious stress, this is just casual shooting on a private range. Under real stress it’s very common for people, even trained and experienced soldiers and professional shooters, to forget to pump and then short stroke to ‘catch up’ or even just short stroke period. Until and unless you figure out that you need to cycle the foregrip again to get the weapon back into service, and that’s not always a given nor will you necessarily have time to figure it out, you have a club not a shotgun. Not a great club, either.
Hickok45 demonstrates these problems again later on in the video, and you see it in his other pump gun reviews too. As you’d expect other trained/experienced shooters on Youtube also demonstrate the issue. Even experienced three-gun competitors can fail to pump/short stroke/both under the pressure of competition - which is why semi-autos now rule three gun matches.
It was enough of a problem for the LAPD, even with veteran male officers, that they have started converting to the Marines’ M1014 aka the Benelli M4 Super 90.
Thanks for that link !
Good to know; I have a Remington 870 20 ga.
