12GA. VH

[Scott Gentry]

Every so often my VH SST (factory trigger) will fail to fire the second barrel. I have seen inside and it is pretty clean, not the mess I was expecting. When dry firing it goes click/click every time. When I first got the gun the selector would not move, one small drop of oil and 1 hour later it broke free and now moves freely. Some days it will run 50 rounds and no problem, other days it will fail 3 times in 25 shots. Seems to do worse on cold days, may have nothing to do with it. ????Any thoughts?

[Robin Lewis]

It could be the oil is thick due to the cold and/or some of the old oil has mixed with the new to make it thick too? It seem that you are willing to "go inside", I would suggest you give it a good cleaning and keep it dry of oil. If you do lube it, use a product that will not change viscosity in the cold or gum up with age. Maybe, powered graphite? I'm not a gun smith but several read this forum, maybe one of them will suggest a better product to use. The symptoms sure sound like bad lube gumming up the workings.

Single trigger is prone to be the problem, probaby some oil in the trigger, these triggers cannot have any oil, even the hang tags from Parker said do not oil. So I would suspect there is oil on the single trigger and in cold weather hanging up the weighted balance that switches the triggers. Eric

Thanks, how should I remove oil if present?

[Dave Suponski]

Brake Clean does a very good job of removing oil on single trigger guns.

[Scott Gentry]

Thank You

[Eric Eis]

Scott, make sure you don't get that brake cleaner on anything but the trigger housing, if I am not mistaken it will take of the blueing and may affect the case colors. Eric

And it will take varnish off the wood.

[Dave Suponski]

These guy's are right. I should have mentioned to take the stock off! Sorry....:banghead:

[Scott Gentry]

will do, thanks to all, this thing being a single shot when the mallards are coming in is a pain. For some reason does not seem to happen on trash ducks, just when group of mallards are at 20 yards.

[Scott Gentry]

ok removed trigger and cleaned, (twice) will fire both barrels if shooting ground levels up to 45 degrees, 45 to an overhead shot it is a single shot. Think it may be a weak spring. Same results no matter which barrel is selected to fire first.

Help.

Are you sure you're not shooting a M12 3" Superspeed gun? Comon malady for them, which I don't think was ever resolved.

[Scott Gentry]

The model 12 heavy duck had issues with the feeding of shells on overhead shots( shells falling out of ejection port), the problem was fixed with a guide on the carrier. My current problem is quite different.
