I bought a winchester 1300 (pump action)12 gauge new at a gun show awhile back. Shot it some and never noticed any trouble the first time out. Second time it seemed like it popped once but I wasn't sure (was shooting trap/target loads both times).
Yesterday I tried shooting some plain old winchester 2-3/4" slugs out of it and it was blowing open. Stuck a trap load in and it did the same thing, only it doesn't blow the action all the way back. Just pops it open part way.
I couldn't break the action loose by hand. Wouldn't budge without hitting the releasem, so it is locking just not staying locked for some reason :confused: :cuss: .

So I took it apart, and everything appears OK. There isn't anything obviously broken. I'm wondering if this could be caused by not assembling it correctly? The first couple times I had a lot of trouble getting the trigger group back in. It didn't want to line up correctly. When I put it back together this time the trigger group popped right into place with no trouble. I'm tempted to go try a trap load in it again and see if it still pops open.....but thought I'd try to get some opinions in here also. So is it possible that it was just an assembly issue?
The paperwork I got with it is the universal manual for winchester pump guns. The bridge plate and extractor don't match up to the diagrams, and I was told it was because they had been updated. So I can't really get much insight from them on seeing what is wrong with it since the pictures pretty much suck and I don't know which parts are correct anyhow :banghead:
Thanks for any advice :)

The Winchester 1300 is famous for this feature of the gun.

I "think" Winchester calls it the 1300 "Fast Action" or something like that.

The Winny rotating bolt more or less has an assist function that causes the bolt to open much easier.

Many people like it since the gun operates so fast.

Most pumps will do that when broken in or honed out. Gough Thomas clamped weights on the foreend of an Ithaca 37 until he had it to where it would kick itself completely open and all he had to do was close the action on a new shell. Ruined the balance, of course, which an Englishman could not bear except for the experiment.

I don't know reading what he says it doesn't sound like the normal Winchester feature. Correct me if I'm wrong but it sounds like after a shot that he has to hit the slide release to be able to pull the slide back at all.

If you were describing the slide coming back a little after a shot and it therefore being easier for you to pump the gun then you'll have to forgive me for thinking it was something else.

No, when I said I had to hit the release button I meant prior to firing. The slide does seem to lock up just fine.
Its after shooting that it flies open. With a trap load it brings the slide about halfway back. With a slug, it was actually ejecting the empty shell and picking the next one up onto to carrier.
The action has slicked up quite a bit, and I did lube it with a little bit of SAE 30 oil on the rails before last time because I wasn't happy with how Rem Oil was working in it. So maybe it is supposed to be doing this. I've only shot 3-4 different pump guns and had never seen anything like it before though....don't know if I can get used to it or not.

Thanks for the help everybody:D

Ok I guess I read it wrong then, my mistake. Anyway my 1300 doesn't quite eject the shell like yours does with slugs but it definitely does unlock and come back some.

[TarpleyG]

That's the Speedpump feature of the rotating bolt. Wait until it gets good and broken in--the empties will eject themselves from time to time. If you get used to this and let it work, it is extremely fast.

Well I don't know how I missed that stuff when I read ads about the gun....but I looked it up on winchester's website and you guys are right as usual. Haven't gotten a chance to shoot it again yet, but it sounds like it might be kind of fun if I can get used to it.
So from now on when I talk about it flying open, I'm braggin not complaining :rolleyes: :D
Thanks again

After a few thousand rounds, mine will fully eject light trap rounds if I don't hold onto the forarm. If I do it is dange close to being fully open.

It's a poor man's semi-auto.

Shoot some turkey loads or HV slugs, your shoulder hurts and you only run the action forwards.

Ive got an 18 inch defender. Its good looking, has an 8 shell capacity, and is very smooth and fast to operate.Id estimate it has under 500 rounds through it to date, but it will fully retract the slide with reduced recoil buckshot. When I first shot my roomates mossberg I thought it was broken, or needed to be lubed!

Slamfiring a Ithaca 37 or a Win 12 or 97 is a poor mans semi auto:D

The Winchester 1300 has many parts in common with the
similar Winchester semi-auto: the rotating bolthead will
stay locked in the barrel until the pressure has dropped
to a safe level. I have a S&W 916A that functions very
similar, in that it will open in recoil without touching or
holding the pump handle at all. For years I have heard
of 1300s doing this; it seems to be a bonus feature.

-------
Edit: The Model 1200 pump and 1400 semi-auto were
the ones I was thinking of: the 1300 and 1500 appear to be
variations. The Model 1200 was described to me years
ago as designed to be fast action for a pump.
