Do you mean a Taurus 92 (very similar to the Beretta 92)? I've never heard of the Taurus 91, but I don't know everything I suppose.
If you're talking about the Taurus 92, I had a model 99 a few years ago (same model but with adjustable rear sights) that functioned flawlessly and proved accurate. However, like the Beretta, this model doesn't fit my hand, so I traded it for something else. Overall a fine pistol.
