Larry,
My gun was a Gaspar Arizaga and had a single trigger. One issue was the single trigger, but the other issue was the sears, lifters, and hammers were all very crudely made, did not match in size (left to right), and were very soft. It may sound hard to believe but the metal was so soft I could bend it in my hands. The barrels however seem to be of good quality. Have to admit, however, when I bought the gun I was attracted by the exterior flash.
But there are just too many other good, inexpensive guns out there for just a few dollars more. Several examples would be an older Ugartechea M-30, a Victor Sarasqueta SLNE imported by Stoeger, the Urbiola SLE on gunbroker for $700 (Thad Scotts), and an older AyA, etc... I have taken apart all these guns and there is a world of difference in the interior quality.
Leave the G. Arizaga to the cowboy shooters to chop up.
