CowCow Technology Steel Hammer Set

No, this specific hammer set is engineered exclusively for Gen 3 Elite Force and UMAREX GLOCK 17 and 18C models. It will not be compatible with Gen 4 or Gen 5 internal configurations.

The stock hammer is typically made of a softer alloy that wears down over time, leading to inconsistent cycling or trigger issues. This stainless steel version is CNC machined for higher durability, which reduces friction and ensures a more consistent, reliable hammer strike.

While it is a direct drop-in upgrade, it does require a complete disassembly of your pistol's lower frame. If you are comfortable taking apart your trigger group and sear assembly, you should be able to install it, but we recommend having a basic set of airsoft tools and a reference guide handy.

This hammer set is primarily designed for durability and smoother cycling rather than modifying trigger pull weight. While the reduced friction can make the trigger feel slightly smoother, it is not intended to act as a trigger tuning kit.

It is not strictly required, but it is good practice to inspect your sear and hammer spring while you have the pistol disassembled. If those parts show significant wear, replacing them at the same time will ensure the entire system functions optimally.
