The BSS guns have mechanical triggers. However, as most "mechanical" triggered guns, there is still an inertia mechanism in there, to keep the gun from doubling. It doesn't require the recoil of a shell firing to set but it briefly disables the firing of the second hammer during the recoil of the first shot. The parts still need to be clean and lightly lubed. The trigger and link also need to allow the mechanism to move properly, so the second barrel will set for firing.

Could it be an issue with the safety ?

I believe that there are two trigger types for the BSS. The early guns had a Silver colored triger that is Mechanical. Later guns had a Gold colored trigger that is inertia. Mine is silver, and never been an issue.

Silver is the earlier non-selective trigger. The gold one is selective but both are mechanical, TTBOMK.

Is it possible to "trap" the BSS trigger between shots as it is on some Citori's?

It's possible to "trap" ANY single trigger. You've got to release all of them, or they can't reset.

How about, is trapping a BSS trigger "likely", as it is with many Citori shooters?

My 20g BSS Sporter had this same problem and found a solution. If I remember right the selector mechanism worked correctly when the right barrel was fired first, but would not switch to the right barrel when the left barrel was fired first. I had the gun many years without noticing the malfunction because I always had the right barrel selected to fire first. My BSS did not have a selector button in back of the trigger, just the shaft with the hole in it, so it was a little difficult to push the shaft to the other side because of the missing button. It was this way when I bought the gun. After cleaning and messing around for a long time, I put a couple small washers on the shaft of the selector and held them on with a little pin through the hole. The slight repositioning of the selector mechanism allowed automatic switching to the second barrel. Hope this helps, Dan

Of the 4-5 BSS guns I've owned since the seventies, I've shot one or more of them as my primary gun most of the time. My experience is that the triggers on the BSS are among the best in their class of midrange production guns. I've shot well in excess of 15,000 rounds out of one BSS without a trigger issue, and thousands out of a number of other BSS guns without problems. The two exceptions are; a BSS 20g I bought from a member here that the trigger had clearly been messed with by an unknowledgeable hack, causing it to double, and another 20g that a pin in the trigger eventually worked it's way partly out, causing inability to fire on occasion.

I would put the design above the highly held Miller.

As requested I'm reporting on the problem with my BSS single non-selective trigger.

When I got around to pulling off the buttstock I found that it is indeed a true mechanically resetting trigger, as others pointed out. When the trigger is pulled the right hammer falls, then as the trigger is released a light spring pushes the inertia block forward, which in turn pushes the connector forward on the trigger plate setting the trigger to fire the left barrel. Before cleaning mine would reset nearly every time if I smartly released the trigger, but would hang part way forward if the trigger was released slowly. I cleaned it thoroughly with carb and choke cleaner then very sparingly oiled the hinged parts and where the connector slides on the trigger plate. This has completely solved the problem, it seems. Although I could see no dirt or gummed oil in there there must have been something that was not allowing the connector to move as freely as it should.

I also reversed the safety pushrod and disabled the automatic safety while in there. Easy fix, and completely reversible if desired.

Thanks for everyone's suggestions.
