Replace the stock spring cups with maritime spring cups to improve the action break and trigger pull on Glock pistols. The improvement is achieved due to the design of the maritime cups which reduces friction due to less surface area contact of the cups in the striker channel as the strike moves back and forth. These Maritime cups fit all Glock Gen 1 - 4 models.
The novelty ads claim maritime cups allow you to fire a Glock underwater, but we sell them for the purpose of improving the action break of the pistol. We highly caution against firing a gun underwater with or without maritime cups; certainly without proper and formal training.
Price is $9.95.
