They also made copies of other Beretta autos in the Beretta factory they purchased. They made copies of the little tip-up barrel 22's and 25's. I own one of the 22's and it has functioned just as well as my 92 (100%, in other words).
My Taurus "92" is really a Model 99, the same thing but with adjustable sights. I bought it NiB in 1989 or 90, when they were about to pass that stupid high-capacity magazine ban. I don't remember the exact number, but I think I paid $400-something for it OTD with sales tax and everything.
STUPID SEMI-RELATED STORY ALERT: My 99 was an excellent pistol for many years. But I did something pretty dumb with it. My dad was in town and thought it would be fun to go shoot pistols with me. For some reason I decided to invite my ex-GF along, who I had recently broken up with. She hadn't started acting crazy and stalking me and so forth yet at that point, so I figured we could still be friends. Rather than shooting me, she apparently smashed my PT99 against the tailgate of my pickup truck a few times while I was packing up my other guns. When I later noticed the missing rear sight and chipped extractor and so forth, it occurred to me that the gun had a lifetime warranty. Unsurprisingly, Taurus declined to fix the damage for free (hey, it was worth a try), but someone there sympathized with my stupidity and let me have a new slide assembly for a reduced "dealer price". The good news is that it always had a good trigger, and now the rest of it is brand-new.
My FiL likes my PT99 so much that he decided to buy one of those surplus Beretta 92's that were for sale all over the place about a year ago. He knew that it was basically the same pistol with just a few differences. When he got it he was annoyed to find that he didn't like the mag release or safety nearly as much as the ones on my Taurus, and the sights and trigger weren't really as good either. But $299 a year ago is a lot less money than $400-something was in 1990, and he has eventually adjusted to it pretty well. So all's well that ends well.
