Ahjae TV goes over GSI Zero Friction Steel Hammer, a specialized upgrade designed for VFC Glock airsoft pistols. He explains that most airsoft Glocks suffer from a "stiff" slide due to the hammer design, but this steel component aims to fix that while adding some much-needed durability. It’s a bit like giving your toy gun a shot of espresso and a gym membership at the same time.

He takes us through the greasy reality of the installation process, which involves disassembling the lower frame and performing some surgical-grade sanding on the internal parts. He even encounters a broken housing along the way, proving that even airsoft experts have bad days at the office. There’s a bit of trial and error involved in getting the fit just right, particularly when it comes to trimming parts so the gas doesn't decide to leak out all at once.

Once the dust settles and the parts are back together, the results are quite noticeable. The slide moves with a smoothness that mimics much higher-end models, losing that annoying hitch that usually bothers realism enthusiasts. While the installation might make a beginner want to hide under the covers, Ahjae TV says that the improved performance makes it a tempting choice for anyone who wants their Glock to feel less like a plastic clicker and more like a precision instrument.
