    Makes DA trigger pull very smooth

    Swapped out the sear spring and installed the 17lb spring in my mk25. Now my double action accuracy is better than my single action.

    Should of done this sooner!

    Kept looking at this kit but hesitated but now that it is installed I am overjoyed with it and the results are amazing.
    Have a 229 Select that had a slightly heavier than average pull compared to the many other Sigs I own and have owned.
    Installed the sear spring and 19 lb mainspring and with the factory short reset trigger already in it from the factory it is comparable to my Legions.
    DA is very noticeably reduced and I notice the change on SA as well.
    In addition to the reduced trigger pull the DA pull is not only lighter but very smooth from start to finish of pull.
    Installation was a breeze and quick.
    If you are looking to do this to your Sig don’t wait- it is worth the time and money.

    Upgrade to 229 Legion

    Patrick Vernon (verified owner)

    Installed 19# and sear spring in my 229 Legion in about 5 minutes. Was a very easy install with a noticeable difference in DA trigger pull. Quick delivery and worth the $16. Had no light strikes since install .

    Quality Product gets the job done.

    henckelrobert (verified owner)

    I ordered the P Series Master Spring Kit for my 229 E2. My pistol already had the Short Reset Trigger and the internal SRT parts. I installed the 19 lb. spring as recommended for a carry gun and the sear spring. The kit dropped my double action and single action trigger pulls by about 2 1/2 lbs. respectively. Very pleased with the results and quality of the product and service.

    Simple, Effective

    sten25 (verified owner)

    I ordered two of these sets, placing the 19 pound spring in my P228, and a 17 pound spring in my P226.

    After verifying operation at the range for both guns, I found that neither spring affected the amazing reliability of each pistol.

    In fact, my trigger work in the P226 was so notably improved, that after a few months, the P228 was moved to the red spring as well.

    For the money, one of the best improvements I’ve made on my Sig pistols (next to the Gray Guns adjustable triggers).

    Great spring set and fast shipping

    Chris Twitchell (verified owner)

    I was able to accomplish the trigger adjustments I was looking for. After testing multiple springs, I landed on the red spring (17lb spring) and averaged 8lbs. DA. For SA, I averaged just over 2lbs. Installation was not too difficult. There are many installation videos out there to assist if needed. Definitely make sure you either know how to install the spring kit, watch installation videos in advance or have your gunsmith install the kit. If you’re new to working on Sig’s, the install can be a bit tricky and the reassembly can be more tricky if you don’t disassemble properly. Overall, I’m very pleased with the kit and Gray Guns. They make it easy! I would definitely recommend this spring kit.
