870 fail

Buddy of mine has a property of his setup with an alarm. If the alarm goes off, the system calls him. If he’s unavailable, it calls person #2. If #2 is out, it calls person #3. I am person #3. So I was minding my own business the other day and I get a call on my cellphone. It’s the automated alarm telling me something is up. I grab a loaded 870 from the closet and hop in the truck. I get to the property and chamber a round in the 870 and start looking around for broken windows and that sort of thing. Nothing. I let myself into the house, check things, and everything seems fine. False alarm. Not the first time, but you gotta treat each one like the real deal, y’know?

So I press the bolt release on the shotgun and figure I’ll cycle the ammo out of the gun and reload it. (I prefer a particular order of shotgun shells in my magazine tube.) First round pops out and -fail- the next round stays in the magazine. WTF? The magazine follower or spring had bound up somewhere in the tube and was not providing force to feed the rounds down the tube. (This wasnt as failtacular as it could have been. In addition to the 870 I also had my holstered G19 at the time.)

The follower in the tube was this one from Wilson. I’d replaced the factory follower years ago. I went to the range yesterday to test out the shotgun and it kept doing the same thing. I pulled the follower and it had scuff marks all around its circumference. I pulled the spring, removed the barrel, and ran a boresnake (12 ga. size, naturally) down the tube a few times in case the problem was some accumulated grit or something. Nope…same problem after reassembly. Near as I can figure, the follower is snagging or catching at the junction between the magazine tube and the tube extension. (I tried beveling and filing the edges of the Wilson follower in case there were some sharp edges catching….no joy.)

Remington, for some incredibly stupid reason, ran off a batch of their 870s with dimples in the magazine tube that precluded adding a magazine extension. The fix was to simply drill out those dimples. This shotgun isnt one of those 870s. The mag extension is a quality one, not some cheap Chinese crap. I’m fairly confident the problem is the follower. I ordered a stainless steel one (’cause, baby, nothing kills like overkill) from Brownells today and when it gets here I’m hoping it will make the difference. I also need to carefully investigate the junction of the mag tube extension with the mag tube and see if theres any obvious problem there. The nice thing is that I have enough 870s sitting around here that I can swap out parts through process of elimination to narrow down the culprit. I’m 90% its the follower, though.

I’ve another 870 thats been sitting in the bedroom for a few years and hasnt been shot in quite a while. Guess I better check that one out as well.

Moral of the story: it isnt enough to leave loaded guns laying about, you gotta test ‘em preiodically.

  1. Amen to that, any time you swap out a part, if a seemingly cosmetic one, you gotta put it through a function test. Preferably a rigorous one. Glad this one turned out alright.

  2. OUCH! My Winchester used to give me fits when the shells would sort of “stall” coming out of the magazine, causing FTF. Found out that while the barrel might SAY the weapon takes 3″ shells, those are the only ones that are hanging up coming out the magazine.

    No more 3″ shells in the Winchester…

  3. I have three model 870 shotguns, with different barrel lengths. Two have magazine extensions. I’ve never had a problem with them so I can’t think of anything you haven’t already covered in terms of what could be causing the malfunction. Good luck with getting it squared away.

  4. My 870 problems have been confined to followers allowing the 2nd shell to follow right behind the loaded round, (behind the gate), locking it up. Only recourse is to use knife point to push shell back into magazine – that is a show stopper too!

    Sounds like the shell stops or the related spring needs replacing.

  5. IMHO whenever you add after market parts to anything you ask for problems

    I agree, but sometimes the factory part just doesnt meet the need. We’ll see when the new follower gets here.

  6. According to Remington all 870 Express Models manufactured since 2007 should have the two dimples and new style of follower and some Magnum and Wingmaster models have them as well. When I built my newest home-defense based 870 I ran into the dimple issue right off the bat and had to grind them down with a Dremel tool.

  7. I believe those dents that Remington put into the magazine tube are the to make sure that when we disassemble our bird guns the follower doesn’t leave for parts unknown. Either Midway or Brownells sells a tool to remove these dents.
