My brand-new MNP 9 mm Pro has been jamming frequently. I picked up the gun last Monday and shot 100 rounds at the dealer's indoor range. The gun jammed three times during 100 rounds, I attributed the jamming to a "tight" brand new gun. Today I shot 100 rounds and the gun jammed at least 10 times. The jams were primarily due to incomplete ejection of spent casings. Is frequent jamming typical of this gun during the “break-in” period?

The first 100 rounds were PMC and the second 100 were Federal.
