Beretta Recoil Spring Assembly Features The Beretta D-Hammer spring is a steel recoil spring assembly engineered to reduce the double action trigger pull effort on compatible pistols. Heavy double action pull weight is one of the most common complaints among shooters of double action/single action Beretta pistols and this spring directly addresses that by lightening the effort required for the first trigger pull. Because the spring installs in seconds shooters can improve their trigger feel without a gunsmith visit or specialized tools. A lighter more consistent double action pull translates directly into better first-shot accuracy for both range use and duty carry. This spring is built to fit the PX4 series along with the 92 series and 8000 series pistols giving owners of multiple Beretta platforms a single replacement part that works across their collection. Steel construction ensures the spring holds its tension reliably over repeated cycling maintaining the improved trigger feel over the life of the part. Because it is a factory Beretta component fitment and function match the pistol s original design intent rather than requiring aftermarket tuning. For PX4 owners looking for a simple inexpensive way to improve double action trigger feel this recoil spring assembly is a straightforward upgrade.
