  We present the results of X-ray spectral and timing analyses of the closest
gamma-ray emitting narrow-line Seyfert 1 ($\gamma$-NLS1) galaxy, 1H 0323+342.
We use observations from a recent, simultaneous XMM-Newton/NuSTAR campaign. As
in radio-quiet NLS1s, the spectrum reveals a soft excess at low energies
($\lesssim2$ keV) and reflection features such as a broad iron K emission line.
We also find evidence of a hard excess at energies above $\sim35$ keV that is
likely a consequence of jet emission. Our analysis shows that relativistic
reflection is statistically required, and using a combination of models that
includes the reflection model relxill for the broadband spectrum, we find an
inclination of $i=63^{+7}_{-5}$ degrees, which is in tension with much lower
values inferred by superluminal motion in radio observations. We also find a
flat ($q=2.2\pm0.3$) emissivity profile, implying that there is more reflected
flux than usual being emitted from the outer regions of the disk, which in turn
suggests a deviation from the thin disk model assumption. We discuss possible
reasons for this, such as reflection off of a thick accretion disk geometry.
