These are made by KCI and a quality replacement magazine for a Glock. Glock magazines have a hardened steel insert which is encased in a high tech polymer (which is fully metal lined). The polymer coating protects the gun magazine and prevents deformation, even when dropped from great heights.
For best results KCI Mags recommends loading half of the magazine capacity and leaving it loaded over-night before your initial use. This will help with future loadings of the gun magazine and make it easier.
It may not be possible to initially load them to capacity. Loading half of the listed capacity and leaving it loaded overnight before the first use will ease future loadings. This item is sold (as is) since it is an aftermarket Korean magazine and not a Glock factory OEM magazine.
We will not ship this item to the following locations:
California, Hawaii, Maryland, Massachusetts, New Jersey, New York or Washington D.C.
If you place and order for a High Capacity Gun Magazine from a restricted state your order will be canceled.
