IOW they couldn't even hold a close enough tolerance on a mass produced gun to guarantee that a factory mag ( list price 67.50$ ea. last time I checked) would fit.
My first hand experience W/ Llama is that the are , essentially , Spanish Lorcins. They are made from cheap, soft pot metal & quality control was (obviously) nonexistant in the plant.
Even the people that say they got a good one ( no offense) are shooting a pot metal gun that is likely to blow up in their face one day. (Again first hand expreience)
1) The magazines had slightly different specifications because the models were slightly different. They were never Mil-Spec guns, until the M82. As years went by, the guns were updated.
2) Unless, and until you can explain in detail how you arrived at the "pot metal", which is an actual term with definition, title, you're giving us opinion declared as fact. As for the soft metal myth, that was from WWI, and the Ruby pistol. Llama, like Astra, was a much smaller company. Actually, more of a loose group of gunsmiths. The orders from France rapidly outstripped the ability to manufacture the guns, and they outsourced to other Basque gunsmiths, who used whatever metals they could find.
3) You have had a bad experience with a Llama "disassembling itself in your hand". Fine, X-frame S&Ws from the first run shed barrels while firing. Does that also qualify them as pot metal guns that disassemble themselves while firing? You're better than that.
4) There is no supporting evidence that Llama firearms are dangerous to the shooter. One incident, or two, in a company that's produced firearms for over 80 years is certainly not proof.

Jane's Guns Recognition Guide dated 1996 says this:
"Well made, of good materials, they were among the best Spnaish (sp) pistols of their day, and many are still in use."
This is a description of the Model IX. Page 88.
Having owned both an XI-B, and a IIIA for decades, I have found that the little guns hold up much better than you would allow. While the IIIA doesn't like many JHP profiles, it will feed those who's ogive resembles the FMJ. The XI-B feeds 9mm rounds like just about any other 1980's pistol, from any manufacturer. No signs of battering, or metal galling or smearing in either.
