The 9mm Beretta is a fine weapon, it has a very heavy trigger pull however. You can change the mainspring for a reduced power spring from the D model to drop the double action pull from around 12 pounds to 8 pounds. Single action will remain at about 5 pounds.
The .40 cal Beretta 96 suffered from slide cracking, resulting in the Brigadier model with a heavier slide. This has a removable front sight as well, allowing you to change out for night sights or a fibre optic front sight. The brigadier also came in 9mm.
The 90-Two is the new polymer gripped version of the 92/96, with the removable sights of the Brigadier.
Basically they are a fine, reliable firearm. If you want to compete in IPSC they are not the best option, but Slavex (a moderator on this forum) managed to make the Canadian team while shooting one.
Beretta also make a .22 conversion called the practice kit for cheap training, I have one and find it very reliable.
