Gas port issue with mossberg 935 slug barrel

I have one and have never heard of it , if you look down the inside of the barrel the ports are quite visible. If lead slugs were used maybe this plugged the ports if so just take a paper clip and poke it into the port to clean it out. Just a thought did you remove the gas piston before you looked for the ports?
 
Yep pulled the piston. It is a deer/ turkey combo gun. I cleaned the ports in the turkey barrel with a paper clip no problem.

Had my son out shooting on Saturday the slug barrel would not eject empty's, come to think if it it never has. Bought the gun used haven't really ever used the slug barrel. Now I tried cleaning with a paper clip. I will not go in at all. The Ports are there but don't look to be drilled all the way into the barrel can not see them in the barrel even when I shine a light through the ports ???
Let the ports soak overnight in some solvent still no go with a strong needle???? Kinda stumped I am going to contact mossberg tomorrow see if they can give am any info.

Just wonder if anyone else has ever experienced this?
 
I don't own a rifled barrel but I do have some smoothbores you should be able to see light through the ports , the holes are drilled on an angle so you could redrill them if you wanted to.
It may also be an issue of the pressures getting past the ports within the grooves of the rifling
 
Its too bad manufacturers don't take the few minutes to test a gun for feeding and function but I guess it would take $2 from the profit margin.

It is kinda sad,
The part that bothers me most is the time required to repair or replace here in Canada. The smith at Wortners was explaining the headaches in getting replacement parts and warranty parts from the U.S. Now I know why there are so few true gunsmiths in Canada. Sounded utterly frustrating for them.

I hope I can get it back before the November deer hunt??? but not holding my breath.
 
Have you contacted Grech outdoors? They are the approved Canadian warranty facility for Mossberg. They may be able to either replace the barrel or complete the work quicker. I have no personal dealings with them, but as mentioned, they are the authorized mossberg warranty facility
 
Mossberg is great to deal with they have to be cause some of those 935's are junk when they work they are great at dropping birds but there's to much plastic in the internals of the gun .I no cause I own one but I never heard of a slug barrel for it is it over bored or a regular barrel .

The slug barrels are not overbored and they are rifled. There are two types of rifled slug barrels for the 935. One has a cantilever scope mount and one doesnt.
As far as your comment about plastic, I dont know about your gun, but the only plastic on my 935 are the synthetic stocks and the forearm spacer. Nothing in the internals is plastic...not even the magazine plug...that happens to be a 1/2" wooden dowel. Care to elaborate?
 
Yeah I'll elaborate the gas piston in mine is plastic and it cracks down the middle all the time but it keeps caulking I heard they revamped the newer ones.I liked the gun but when the trigger group went down it went to the smith in the middle of the season that was it for me.

I've never heard of a gun having a plastic gas piston. My 935 has steel piston with 2 steel rings on it. My 935 was manufactured in 2008 so its notnanrefent model
 
I meant the plunger the part with the two rods that drive the bolt back I can't find my manual for the correct name but mine is made of plastic and it's cracked down the centre I have a spare but I don't use the gun much anymore.I keep it for backup in case my gold 10 ever goes down I like the over bored barrel it's basically a 10 guage that fires 12 guage shells

The 935 definately had some plastic parts in them in critical locations and they were breaking. So much so others made aluminium replacement kits for them. No idea what mossberg did with the latest ones to fix the problems
Just google plastic parts on these guns and you will see lots of complaining on stuff like the forearm retainer and/or the pusher assembly as an example.
No GOLDS here my friend :)
Kill all them dam geese will you. Field is full behind the house
Cheers

I did contact Grech but wortners was closer to me.
 
Guys the plastics I was referring to,....... I thought some of the plastic from the sabots may have plugged the gas ports. The 935 has some plastic but overall I have no complaints. Just that undrilled ports are hard to diagnose, as you would expect the mfg'er not to miss something like that. Hopefully repaired soon?
 
Oh right, I forgot about the pusher assembly. My pusher is made of some sort of composite, its not cheap plastic. As mentioned earlier, my gun was manufacturered in 2008 so im not sure if guns made prior to 2008 used a different material. I've dropped my pusher assembly a few times and its appears to be very well made. In fact, its no different then the pusher assembly used on my Browning Silver or Winchester SXP which are also both composite. The only component on my gun that is truely plastic is the forearm spacer. I've heard that the spacer was prone to breaking, but that was usually due to incorrect installation. I've never had an issue with mine.
