Product Description

CGW 11.5 Pound CZ SP01 / Shadow 2 Reduced Power Hammer Spring by Cajun Gun Works

Very popular music wire 11.5# hammer spring color coded “black”.  Must be used with our reduced power firing pin spring, part number RP-FPS.

TECH TIP:  Never change the hammer spring only or mis-fires are certain.  You must balance your springs for reliable ignition.  The CGW reduced power firing pin spring is the perfect match for our HS-12000.

NOTE:  HS-12000 is a competition spring and is not recommended for any self-defense application.  HS-12000 is deigned to be used with Federal and Winchester primers, other brands of primers may not run 100%.  We suggest you thoroughly range test this spring with other primers to verify reliable ignition.

  1. Love this spring

    Posted by Unknown on Dec 4th 2019

    I run this spring in a few CZs and have had 100% primer ignition after many (15k+) rounds. It helps the DA trigger tremendously, and is a great upgrade.

  2. Big difference small coin

    Posted by Earl on Feb 6th 2019

    Installed in a P120 to replace a 13lb, DA went from 8lb 5oz to 6lb 4oz, SA is 3lb. 500 rounds of WSPs zero light strikes. Pretty happy with it.

  3. Transformative and cheap!

    Posted by Aaron In Texas on Jan 14th 2019

    Dropped this in to my Shadow 2 along with the extended firing pin. The difference is huge! As far as cost-efficient trigger mods go, this one is a must-have upgrade.

  4. Trigger job on a dime

    Posted by William on May 3rd 2017

    An alternative you can use while saving some money for a real trigger job. Single action went down to 4 1/2 pounds. (Double action not measured). Not a single light strike (make sure to change the fire pin spring for a reduce power spring as well) Not a single light strike or misfire regardless the ammo i was using. (Several commercial brands from US and foreign countries) Highly recommended..

  5. CGW 11.5

    Posted by Unknown on Oct 26th 2016

    This spring reduced my DA pull by over 1 1/2 lbs and SA by slightly over a 1/2 lb. Well worth it. Have not had any light strike issues.
