Questions
Which insert do I need?
Match the insert to your mag's capacity: 10-round, 15-round, 21-round (20+ double-stack) or 21-round 2011. You need one insert per mag. Not sure? Ask us with your mag model.
When does my pre-order ship?
9mm pre-orders are estimated to ship by Dec 15. If your order includes a pre-order item, everything ships together once it's ready. Orders with only in-stock items ship right away.
Do I need to take my mag apart?
No. It loads through the top of the mag, the same motion as loading the first round. No tools, and your mags stay assembled, even with base pad extensions.
