Popular options include tritium night sights for low-light performance and adjustable sights for fine-tuning the point of impact.
Firing Pin Assembly
The Firing Pin Assembly is responsible for igniting the cartridge primer. This critical component consists of the firing pin itself, along with the firing pin spring, and the firing pin safety. The firing pin is engineered to deliver a precise and powerful impact to the primer, initiating the combustion process. The firing pin spring ensures proper firing pin return and contributes to overall safety.
Extractor
The Extractor is crucial for pulling the spent cartridge casing out of the chamber after firing. It grabs the rim of the casing and extracts it as the slide moves rearward. A properly functioning extractor is essential for preventing malfunctions and ensuring consistent ejection.
Ejector
The Ejector is mounted in the frame and interacts with the spent casing to kick it clear of the firearm. It works in concert with the extractor to ensure that spent casings are ejected efficiently and reliably.
Barrel
The barrel is another critical component that works in conjunction with the slide. The barrel provides a contained chamber for the cartridge and channels the expanding gases of the burning propellant, which propels the bullet down the barrel and out towards the target. The barrel is securely locked into the slide during the firing process, ensuring that the high-pressure gases remain contained.
Performance and Notable Features
The Glock 20 Slide Gen 4’s design contributes significantly to the overall performance of the handgun. The DRSA in particular plays a crucial role in recoil management.
