First, with SparkIV, export your WEAPONS.ivaud from resident.rpf (find it in
pc\audio\Sfx). Open the WEAPONS.ivaud with GTA IV-aud and import all sound files
to here (match the names):

UZI_SHOT3_A_L
UZI_SHOT3_B_L
UZI_SHOT3_C_L
UZI_SHOT3_D_L
UZI_SHOT1_L
UZI_SHOT1_R
UZI_SHOT2_A_L

Save once done and import back to resident.rpf, Save and close.
