SRS-2 Short Reset System
This is a “Master” kit that allows you to tune your CZ for self-defense, range, or competition use. Includes: HS-12000, 11.5# (black) hammer spring for competition and HS-13 (blue) hammer spring for self defense. If you do not intend to use your CZ for competition, then our SRS-1 would be the better, less expensive choice.
Also includes a reduced power firing pin block plunger spring, 61100 tempered spring steel firing pin retaining pin, firing pin lifter arm spring, “low-lift” 61050 firing pin w/spring, and our “short” arm lifter w/spring.
Shortens the SA reset an average of 40%. HS-13 hammer spring will reduce the DA pull weight 40-45% but still retain reliable ignition. The competition only HS-12000 hammer spring will reduce the pull weight 50-60%, but will require the use of mainly Federal primers only.
TECH TIP: We suggest a 3mm roll pin punch for removal of the firing pin retaining pin from the slide. Use this same punch as a guide for lining up the flats on the firing pin, then drive in the new Cajun Gun Works 61100 tempered steel firing pin retaining pin from the left hand side. Be sure and orient the 61100 with the open end “up” at the 12 0’clock position.
HS-13 is the choice for self-defense and produces 100% reliability. Our HS-12000 11.5# hammer spring will ignite the majority of primers in most pistols, but not all, a great choice for competition, range, and when you use mainly Federal primers. Do not mix any CZ factory springs with this kit. Do not use a hammer spring heavier than 15#’s with any extended firing pin.
