As to your question specifically, yes. 115 grains is the only projectile weight that I shoot, when it comes to 9mm, and I shoot it my Baretta Nano. No problems at all.
Specifically, I use Berry's 115 grain plated bullets.
At 115 grains, the round requires more pressure (i.e., more powder), to fully cycle. At lower pressures, I encountered problems, such as short stroking and double feeding.
I've shot about 2000 rounds through it, and never a jam or a stove pipe, once I upped the charge.
