Mizz Maddie,
I have owned several of the BERETTA 92S and they are a great bargain of a pistol. That said, I avoid using +P or +P+ in them. As far as I can find, the 92S was NOT +P RATED. That is really not a problem in my opinion.
I use REMINGTON 115 grain jhp (jacketed hollow point) in 100 round boxes. They are cheap enough at approximately $30.00 a box in 100 round boxes at WALMART.
You can also use the REMINGTON 115 grain ammo for self defense. It is not as good as the premium loads listed below, but from the 4.9 inch barrel of a BERETTA 92S, the bullet will expand and the REMINGTON bullet is a 100 % reliable feeder in every gun I have tried it, except for a SIG P6, which is notorious for this.
For carry ammo, I use FEDERAL HST 124 grain jhp. This is a proven load (in police use) and you can buy 50 round boxes, also for about $30.00 a box, if you shop the internet. Both REMINGTON Golden Sabre and SPEER Gold Dot are also good choices, but usually more expensive unless you can find 50 round boxes.
I found the old style, narrow sights, one sided safety and the "heel" magazine release buttons of the 92S to be little odd, but found the gun will shoot well and very reliably.
