Pump-loading issue with Remington 870 Express Super Magnum?

I just bought this thing a few weeks ago and haven’t even put 100 rounds through it and every once in a while, the shells won’t load out of the magazine tube when I pump the action. I then have to disassemble the action and put it back together, and the problem resolves itself. I looked on the Schematics for the gun and found that the problem part is the “left shell latch” (which doesn’t even latch onto the shell in the first place like the right one does), which slides over too far onto the shell and will not operate like it should when the pump is moved backward. Anyone else had this problem? Is this something to send back to Remington for warranty repair?

Two common possibilities…

That same problem happens when you do a thing called “short stroking the pump”. Are you sure you’re not short stroking?

The two shell holders don’t work at the same time….they work one after the other. They’re tripped at different moments in the pumping/c*cking cycle. Pump your gun slowly and watch the parts move one after the other and you’ll see the last part of the backstroke releases the shell from the mag onto the lifter.

Next time that happens, simply close the action, dry fire it to decock it, and then JERK the slide back. It should load just fine.

Second possibility….

When you stripped it down the last time, are you doing it via the manual? If you removed the trigger group *before* the bolt etc were removed, the shell latches can come unseated from the guide slots. To remedy that, simply strip it back down and reassemble it via the manual ie trigger group back in first, bolt next etc.

If neither of those work, call Remington. It’s a rock solid gun, but even rocks gets broken sometimes.
