The Beretta 92 had a rep once upon a time for slide breakage. You don't hear about it as much anymore, but as far as I know the US Military still mandates slide replacement fairly frequently on theirs? Somebody else might be able to confirm that. FWIW, the Taurus model, which has a preferable safety afaik, never seemed to have the slide breakage problem.
As an aside, I had a couple model 21's that were both decent little guns (though they were purchased years apart and as with many manufacturers, quality had declined noticeably), but once had to deal with beretta's customer service in regard's to a new rifle I had purchased, and it was an extremely negative experience, to say the least. I have sold all my beretta's and wouldn't buy anything else from them just based on that, fwiw. If you get one that works/isn't defective, they are fairly decent, though a bit pricey perhaps, but man, if you ever have to use the customer service (and I use that word euphemistically) you will live to regret it. Just one opinion.
As afurther aside, if you pay attention you will notice that when Beretta has taken over other companies, which they have done alot of the past few years, they tend to cheapen up the product, but still charge as much or more for it, which I think says something. Look at the Tikka Whitetail vs the T3, if you want an example.
