Mossberg 500 Shotgun Trigger Upgrades | Gun Talk Radio
This video discusses a trigger spring kit for the Mossberg 500 shotgun from M-Carbo. The kit includes a hammer spring and trigger return spring designed to reduce trigger pull weight from approximately 8 pounds to around 4.5 pounds. While not a full trigger replacement, it offers a significant improvement for a relatively low cost. The video suggests an optional trigger assembly tool for installation and notes that M-Carbo may provide installation videos.
