Please permit a general comment on Spanish guns and production methods, since they will have a bearing on the decision on whether to buy the guns.
With the exception of a few companies like Astra, most Spanish firearms production is still literally a cottage industry. A factory makes a part as a rough casting or forging. When some of these are made, they are taken to one or more home workmen who grind and file and fit the part to a jig, and return it to the factory, where it is fitted into a gun. Then it is removed, hardened, finished, or whatever. The gun is then assembled, with maybe a little more hand work, and packed for shipping.
But note that part about hardening. If the gun is to be sold really cheap, that part may be skimped. The gun will work for a while, and then quit.
The problem in all this is that parts are never interchangeable. Worse, when something breaks, say a hammer, the spare part the gunsmith gets is the rough forging from the factory. The American gunsmith can certainly duplicate the work of the Spanish home worker, but believe me he gets a lot more money per hour and the part ends up costing enough to make the customer very unhappy. This is not a Remington 870, where all the parts drop in and fit; this is the Pride of Spain!
