Break-In Period

New Glock magazines can require a break-in period before reaching full operational capacity. When new, the magazine spring is stiff, and you may find the final round difficult to seat. This is normal and not a defect.

To accelerate the break-in process:

• Load the magazine with five rounds and leave it loaded for several days to allow the spring to compress naturally
• Cycle the magazine repeatedly from full to empty
• The spring will gradually relax and accept the sixth round more easily

This break-in period typically resolves itself with normal use. Patience during the initial phase ensures your magazine will perform reliably for years to come.
