Winchester 1300 problem

So I recently changed my foregrip from the wood to a black tactical grip. I wen to the range today and started off with 3 mis-fires. I figured I jacked something up, so I stripped it down and put it back together and still had the same problem.

After much frustration, I found there is about an 1/8" of play in the foregrip once I have chambered a round. IT will fire it I hold the grip all the way forward but if I let it come back that 1/8" it will not...I assume that little movement is not allowing the firing pin to strike the primer...but why?

I know I am missing something, but I don't what in the world I could have done?
 
may sound stupid, but could you add a spacer of some kind, or even a steel washer to take up the gap. Just sayin'... :confused:
 
Maybe I didn't give the best description...it is not just the grip moving...it is the bolt and everything...it only fries when everything if forced as far forward as possible. It wants to naturally rest about 1/8" from all the way forward..if that makes sense
 
I took it to one here and he blamed it on user error! It's definitely not user error! He did not live fire it any, but said he spec'd every part out and everything seemed fine...I will be trying another one in the area whenever I pick it back up...
 
Can you take a pic of this and post it? Sounds like the bolt isnt coming forward enough for it to close and lock up.
 
I don't have the gun here tp take a picture of.

Imagine you are looking at the ejection port, you chamber a round successfully, and the forearm is locked into the forward position.

At this point, the weapon should be ready to fire. If I press the trigger at this point, it will only fire if I consciously hold the forearm toward the end of the barrel. If I try to fire it from the position the forearm wants to rest, it will misfire.

The only thing different about the scenario is consciously pushing the forearm forward that 1/8' or so. You can see the bolt/ejection port moving when the forearm is pushed forward.

check the side supports on the inside of the gun that hold the slide arm into place. Ive had these break before and not allow the slide to lock into place or not allow shell ejection.

if thats the problem these pieces can be found for 20-30 bucks.

hope that helps
 
Sence you say play in the bolt I would suspect the bar that locks the bolt foward when you have the hammer inside the gun cocked...
Just my 5 cents
 
I just replaced my corn cob (police style) synthetic fore end on my Remington 870 with a sythetic sporting style fore end and took a look at the manual for the Winchester 1300. They seem to be similar.

When you removed the original forend you had to remove the "slide arm cap" from the slide arm extesion. See parts 45 and 46 in the pdf. http://www.midwestgunworks.com/page/mgwi/ctgy/winchester-model-1300-parts


You will also see a part that is not numbered that looks like it could be a washer or a shim. Did your 1300 have one?

I wonder if you tightened your slide arm cap down all the way of if you are missing or need a washer or spacer. I would have thought the gun smith would have caught this but it seems likely that the problem is that becasue of the lack of a shim or the cap is not down all the way that your bolt is not fully forward to where it can lock.

This is a real SWAG since I have never even held a 1300.
 
Also have you tried putting back on the old foreend to see is the problem goes away. But the bar that pops up to lock the bolt when the hammer is cocked would be my first asumtion due to the bolt being able to only move 1/8th inch if I hear you correctly
 
Yes, it only moves that much once a round is chambered. I will find the manual and check for a washer but I don't remember a washer or spacer anywhere.
 
SharpTJ, I am not sure what that washer is all about in the parts diagam. I watched a video of a long forearm being taken off of the slide and saw no washer/spacer.
 
You do know Winchester famously called the 1300 "the speed pump"? It was designed to partially unlock a millisecond after firing and provide rearward momentum to the action/bolt so that the shooter could cycle the gun faster. Perfectly safe if operating properly. It was marketed by Winchester as the fastest pump shotgun available.

Now, I'm not saying you don't have a problem with your shotgun. Just giving you some info that you may not have been aware of.

I recently changed the stock fore end on my 1300 Defender. There was a thin washer/spacer on the front. It's about 1/16" thick. I didn't reuse it and haven't fired the shotgun yet so can't say I will have the same problem you have. I purchased my Defender in 1984 and don't know if newer versions have the "spacer".

I was beginning to wonder about whether the spacer even exists but see that dwaad had one with his corn cob fore arm. Still, and assuming your model is like the one in the picure you posted, I am thinking the spacer may be needed to tighten the nut down on some models, but whether you have it on or not shouldn'e affect the bold from locking up. That would be the result of travel and he action bars should travel the same amount with or without spacer s long as the desing is such that travel of the slide on the magaine tube is not impeded

Now I don't know how the Win 1300 is set up, but on my 870 the fore arm nut comes to rest about 1/16" short of hitting the barrel guide ring and if I inadvertenly placed a spacer under that fore arm nut I imagine that it would be difficult to slide the rack all the way forward.

Is it possible that when you took your original fore arm off there was a spacer there but you didn't notice it because it was stuck to the base of the slide nut? Take ths slide off and I don't think you will have to dissassemble it. Possibly you can even leave it on the magazine as long as you take the barrel off so you can feel with your thumb nail and try to catch the edge of the spacer. Use a good flashligt.

The thing is if that was your problem, you tried putting the old fore arm on and it didn't change.
