Smith and Wesson Sigma SW9VE with Apex and MCARBO springs SD9VE and SD9 2.0 trigger pull weight
This video details a trigger upgrade process for a Smith & Wesson Sigma SW9VE pistol, also applicable to the SD9VE and SD9 2.0 models. The owner initially found the stock trigger to be heavy and unpleasant. They first installed an Apex spring kit, which provided some improvement but didn't fully resolve the heavy pull. Subsequently, an MCARBO sear spring kit was added. The video aims to investigate and demonstrate the resulting trigger pull weight after these modifications.
