I hace come across two OUs that had hammer-sear problems, one of them doubling. The first was due to dried oil which slowed sear movement and prevented cocking the top barrel. Ever since that expreience I stopped using drying oils, anything with thinners in it which evaporates and leaves a gummy residue.

The second was a double trigger OU which had some stock shrinkage that was "fixed" by overtightening the grip screws. The tightening moved the trigger plate closer to the top tang and the gun doubled.

Had two different Weatherby O/U's double and then two different Foxes. The factory fixed the Weatherby's. The Foxes were fixed by Dan Rossiter in about 15 minutes by correcting a few internal things. One thing, when a 12 gauge doubles, you damn well know it. All four of these were 12 gauge guns.

That certainly takes some of the craziness out of it, and makes sense, I guess I just assumed it had been correct from the factory.

At any rate I was just throwing a possibility.

Edited to add: the only other gun that I have had double on me was a Felix Sarasqueta with a single trigger, it was just dirty and a good cleaning took care of it.

Back in the late 1950's I had a pre-WWI 12 gauge J Stevens Arms & Tool Co double which began doubling if you pulled the rear trigger first. I pulled the stock to investigate, turned out the left sear tail sat a bit lower than the right one. There was enough wear to the sear pin/sear hole engagement the left sear tail would catch on the right one as it was lifted firing both barrels simultaneously. I did not give it a proper fix of re-doing the sear pin/sear holes. I simply cut a short section of spring from a ball point pin & placed it on the pin between the sears which kept them pushed apart, never had another problem with it. My first gunsmithing project.

It was still that way a number of years later when I foolishly traded it off. I say foolish, not because of any intricate value of the gun, but it was the first shotgun I had personally owned, first double I had ever sot & was the gun which started me down the path of using only SxS doubles. all value was purely sentimental, but I have regretted getting rid of it many times over the years.

When this first doubling occurred I had just shot at a squirrel in a tall tree, so hit the back trigger. I noticed a loud boom, which I attributed to an echo from being under the thick leaves, but noticed no undue recoil. It was a 30" barreled gun of at least 7 1/2 lbs weight, maybe more & I was only firing 3DE with 1 oz of #6 shot. The next time I pulled the rear trigger it snapped & on opening the shell was fired, but not then. I went back to the tree where I had shot that first squirrel & sure enough found the two fired empties there, was not reloading yet.

There are many little thing which can cause doubling which can be determined only by a through investigation. Fortunately "Most" of them are rather easily fixed, though not all are.

Is this a side lock or a box lock Zabala?

most likely problem is as keith described it...spanish gons are known to have soft sears and as such, may wear sooner than later...time to seek professional help...hopefully, cleaning and perhaps recutting of the sear notch and rehardening will solve the problem...

It is a boxlock.
