I was at the range yesterday breaking in my new 870P. A great weapon. But, while shooting some Ranger slugs, the action froze on me. The round fired, but the action wouldn't release until I hit the release bar. I only fired a limited number (getting used to shotguns again) and that was the only glitch. Any ideas on what it could have been?

The only thing I can think of is that your trigger group might be gummed up with old lube or grease; was the action release slow or sticky when you had to use it to open the bolt?

Until Dave checks in:

It's possible your new gun might have a burr left on a part, or some crud from firing could have gotten into the action.

A real possibility is a burr or sharp edge on either the bolt's lock or the locking lug on the barrel.
I usually very lightly bevel the edge of the barrel's locking lug and the top edge of the bolt lock.
Normal firing will break the gun in, and the surfaces will deburr themselves.

Remington recommends that new 870P Police guns be disassembled and sprayed throughly inside and out with something like Rem-Oil.
New police guns are coated with cosmoline to prevent rust during shipping and storage. Spraying the gun down and letting it soak for 15-20 minutes then wiping it off, removes all the cosmoline and allows the lube to soak into the metal, protecting it.

In my experience, this also flushes out any factory crud or metal chips.

In short, it's likely your new gun just needs to be broken in.

Shoulda bought a Winchester I guess :neener:

The guys are on target. First, take it all the way down and remove and and all visible grease. I'd spray the TG dwon with a scrubber and relube lightly.

The Floater about Breaking In New Pumpguns may help.

My bet is that there's some metal filings loose in there and one or more is stopping the disconnector from releasing fully.

Run a few boxes of light loads through it and see if things free up.

HTH...

I knew I'd be told to break it down, but I wanted to get a few rounds through her before I tried that and lost a couple of parts. ;)

[El Tejon]

buzz, not much to lose. The 870 is so simple even El Tejon can tear it apart.:)

[buzz_knox]

I've almost broken flashlights replacing batteries. Trust me. If it can be broken, I can do it.

[buzz_knox]

By the way, did I mention I love my 870? Minimal recoil with tac loads, easily controlled. Much better than my Moss 590. That should stir up some fecal material. ;)

[Dave McCracken]

Don't start nothin', Buzz(G). The Mossistas and Wincheskies are behaving themselves right now and I could use a break.

[El Tejon]

buzz, no you don't! Well, I somehow reversed the operation of a Swedish Mauser putting the bolt together. Hah!:D

[buzz_knox]

You think that's bad? I once saw a Marine reservist do a demonstration of the proper way to field strip and reassemble an M16A2. Once he was done and proudly displaying his work, I held up the recoil spring and said "shouldn't this go in there somewhere?" :)
