Break-In Period

New Glock magazines may feel stiff when loading—this is normal and actually a sign of quality construction. The magazine spring requires a brief break-in period:

  • Load the magazine with all but the last round
  • Allow it to sit for several days so the spring can compress
  • Cycle the magazine from full to empty multiple times to accelerate the break-in process
  • After this period, the magazine will load smoothly and reliably

This initial stiffness ensures your magazine maintains consistent spring tension and reliable feeding throughout its service life.
