Glock Maritime Spring Cups

The maritime spring cups are designed to allow the Glock to be fired immediately after being submerged under water. The channels in the spring cups allow water to escape past the firing pin if the firing pin channel is filled with water. We do not recommend that the Glock be fired under water without proper factory training. Firing the Glock under water without proper training can lead to personal injury and damage to the gun. These are guaranteed to be Glock factory original parts.
