DAK only mainspring replacement
Eric in Arizona
Location: Arizona
Date: July 17, 2025
I purchased this spring for my recently acquired Sig p229 in .40 S&W. I don’t know the history of this particular gun, and since the DAK is double action only, with the only safety feature being a long heavy trigger pull, I wanted to make sure the trigger weight was up to factory poundage. As it turns out, the new spring gave the same weight of pull as the original; 7.5 pounds by my budget trigger scale. The quality of the part is typical Sig quality. Worth the price for peace of mind.
