It would come from New Jersey, not Argentina. However, it is a very rare problem. Well, on a second thought.... perhaps its so rare of a problem that Eagle doesn't keep them in stock and would indeed have to import from Argentina. Hm....My Bersa's Thunder 380+ slide catch just broke today at the range. Just after about 800 rounds. The dealer has some pistols in stock just to be canibalized. Otherwise, we'd to import this part from Argentina.
Has this happened to anyone already?
