Great choice for your first pistole, top of the line gear, love my Beretta inox…. next I recommend a 1911 .45 ACP, even a cheep $350 Norinco if you have to.
115, 124, 147 will run through the inox just fine.
I feed mine 115, and 124. HP rounds same 115, or 124 are fine. As posted by another member it is rated for +P rounds, and once you get comfy with it you can switch up between 115, 124, 147.
Also if your looking for extra mags since you only have 2 that came with it, take a look at Mec-Gar 92fs mags, they are well priced.
