  1. 19 lb mainspring

    Ideal for a trigger job. Not too much pressure on the hammer/sear engagement, but still snaps on release.

  2. Wolff makes great springs

    All of Wolff Springs are great. Cannot buy a better product. DP is also the best.

  3. Great parts

    Posted by Mark on Jan 11th 2018

    Recently purchased gun springs from Dawson, what great service and people. Parts are spot on

  4. Great Product; Great Service

    Posted by Howard on Aug 12th 2017

    Wolff provides quality springs and the items I received performed as expected. It lightened the trigger pull on 2 Kimber stainless pistols -- one in 45ACP and the other in 9mm.

    Even more impressive was the service provided by Dawson Precision -- my order was immediately processed, shipped and received earlier than expected. Unlike their competitor, there were no shipping fees (and nothing extra charged for delivery to HI and AK). I will be back to shop again!

    Smoothed up my trigger job with no creep. Highly recommend this part.

    Easy install and works as stated !
    It's a Wolfe Spring,,,,what's not to like ?

  7. Great for RIA 45ACP FS

    Posted by Ace on Oct 7th 2016

    Replaced stock 23# with this Wolff 19#. Range test was great. Next step is test of stiffer recoil spring. 16# stock to 17# Wolff. Fast delivery. Dawson is the best.

  8. Accurate Spring Rating

    Posted by Mark Staffanou on May 25th 2016

    Since I rely on the accuracy of the various springs I need for my builds, I need to know they are marked accurately. All the 17 pound mainsprings I have purchased measure exactly what they are marked. You can buy with confidence.

  9. Right part, great service.
