+P is fine in that 92, I have shot hundreds through mine along with many thousands of cheapie FMJs of varying weights. I buy the cheapest I can get for general range use and practice with my SD ammo by shooting maybe two mags of it per trip. I am currently using Win. Supreme SXT 147gr. JHP for SD ammo, have used plenty of Speer Gold Dot in the past.
Considering the price of +P I would imagine you are only talking for SD, not thousands of range rounds, in which case you should be fine.
Basically the 9MM are going to be 115, 124 and 147 gr. Any of these are fine although I prefer a 115 for the range (cheaper and easier on the gun and shooter). +P simply means that it is loaded hotter and will generate more chamber pressure.
Hope this helps.
