just recieved my np-30n today and found that the mags when full [10 rds] get stuck when ejecting from the mags well, pull out one rds and the mag falls out fine, there are scrap marks on the mag half way.any ideas on a repair or do the parts just need to wear together, the mags are also tight to load all the rounds into, I'm leaving the mags loaded at the moment to work the spring.
