So I'm at the Fort Bliss Rod And Gun Club shooting my Remington for the first time and the spring or maybe the follower kept getting stuck and the shells wouldn't feed without an upword angle and a good shake. Could the spring be getting caught where the mag ext. meets the rest of the tube? The range safety had know idea what was wrong. Still had a good time and put a 100 shells throught and 100 through my buddies new .380.

Would an aftermarket spring/follower remedy this or would it be a waste of money?

Second its caused by 2 dimples at the end of the stock magazine you haft to grind them or push them down. If you purchased a 870Police magnum remington didnt scimp on the manufacturing of these since 95% of law enforcement use them and put the old style followers which dont require the dimples and preform better.
 
I had the same problem with my 870 express mag. I had to send it back. Came back with a note that said they removed burrs. It only took 2 weeks.
 
tried cycling some rounds through just now. Would feed the first couple, then nothing. I had to shake it to get them to feed:eek: After being emptied the follower was not visible, a couple shakes later it fell into place but without any spring presure. Ok now I started unscrewing the extension and the spring shot down

WTF is wrong with my hallway howitzer:confused:
 
You sure the mag spring isn't kinked or something? When i got mine, I took it apart, and when I replaced the mag spring, it got kinked up and I could onlt put 5 rounds in the tube.
 
Re-install the collar and make sure it is screwed down tight. Then insert the spring and the tube part of the extension and make sure THAT'S screwed down tight.

I'll wager the usual flagon of mead this cures it. If not, then look for burrs.
 
The Remington factory extension is particular about how it's installed.

After screwing the coupling on finger tight, plus ONE "click", screw the extension tube in until it JUST contacts the gun's magazine tube, then install the clamp.

If the extension tube isn't screwed in until it contacts the magazine tube, the spring, follower, or shells can get hung up on the gap.

If the extension is screwed in TOO tightly, the pressure can cause the extension and gun's magazine tube to misalign and cause things to hang up.

Lately, some factory extensions are coming from the factory with the couplings and tubes screwed in so tightly you have to use padded pliers to unscrew them.

Also, check the mouth of the gun's magazine for burrs or out-of-round, and check the threaded end of the extension for burrs or out-of-round.
 
When I got my 870, I had to use plyers to get the cap off. It was unbelieveable. No way did a human being put that on. Even with the plyers, it wasn't easy to turn.
 
While we're on the topic of magazine extensions....would you consider the metal on the 870 express synthetic a matte black or parkerized? I've seen "parkerized" in one of the "Standard Catalog" books as the color, but many of the magazine extensions available through Midway are both black and parkerized. It looks black to me, but I have no experience with parkerized. Thanks :)
 
The marine version is nickle. The Express is blue-over-bead-blasted metal. There are parked versions but not the Express models.
