In the interest of accurate and complete information:

The plating on berrys bullets is by no means delicate
Agreed, but it can be damaged in the reloading process, much more easily so than a jacketed bullet. Not enough bell on the case can easily strip the copper, I've done it a number of times. From the Berry's FAQ - http://www.berrysmfg.com/faq-q13-c1-...d_Bullets.aspx

"Separation is very rare. Two things can cause a jacket to separate from the lead core: excessive speeds (magnum velocities) and a real tight roll crimp (cuts through the plating)."

9mm velocities don't approach the plating separation threshhold at all. No worries.
Many 115 gr. loads are in the 1100-1200 fps velocity range, some are over 1200fps. Again from the Berry's site -

"Velocities depend on the caliber, but as a rule of thumb, we recommend you don't shoot our plated bullets over 1200 feet-per-second. Our 44's actually shoot best around 1150 fps. 45's are generally good at 850-900 fps. "

"Plated bullets occupy a position between cast bullets and jacketed bullets. They are soft lead, but have a hard outer shell on them. When loading plated bullets we have found best results using low- to mid-range jacketed data in the load manual. You must use data for a bullet that has the same weight and profile as the one you are loading. Do not exceed mid-range loads. Do not use magnum loads.. "
