Need help w/ammo

In general, a heavier or lighter bullet is neither good nor bad, it's a matter of having a load that produces a slide or upper velocity in the desired range, and having a matching recoil spring. For normal loads a heavier bullet will typically result in a higher impulse. In the past the 9 mm Parabellum cartridge was most commonly loaded with a bullet of about 124 grains and the 9 mm New Model Luger is set up accordingly. (The Old Model with the flat recoil spring was set up for a milder load with about the same weight of bullet but somewhat less velocity.)

The impulse does not have to be exact, just not so far off the ideal that you are either abusing the pistol or getting malfunctions. otherwise no pistol would operate with anything but a single load.
