For best results SHK Mags recommends loading half of the magazine capacity and leaving it loaded over-night before your initial use. This will help with future loading 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.
