I don't think "overlooking" them has as much to do with it as on-hand availability. Many gun stores simply do not have them in stock with any regularity. The store for which I work (a national chain) carries them, they tend to sell very quickly, but we also get them VERY infrequently. I can literally count on one hand the number of Bersas we have had in-stock in the last year. The other consideration is that we have only seen .380s (they also manufacture 9mm/.40 S&W firearms) come through, and that caliber round is incredibly difficult to find.
Yeah I know. But you don't hear about them as much on gun forums, etc.
These things are the Glocks of South America in terms of popularity, extremely popular. There have been tests with tens of thousands of rounds fired without fail. Stupidly reliable, insanely accurate guns. They aren't "cheap" guns in reality. But they come from Argentina where the US Dollar is really strong. Because of the exchange rate, they end up being pretty affordable for US Citizens.
You just don't hear people talking about them much; unless maybe they are talking about the 380. But they are sweet!
