Glocks are one of the most tested and effective pistols in the world. They are known to be super durable, reliable, and accurate. Glock pistols are also very safe, even though they don't have any external safety. If you are building a Glock pistol and want to use a high-quality safety plunger, you should check out the LANTAC ESP-S Ultra Smooth Safety Plunger and Spring.

Precision machined from 17-4PH stainless steel, this firing pin safety plunger is designed to have an ultra-smooth domed head. This results in lower friction. The plunger also comes with a low-power spring, which can make your trigger pull considerably smoother.
