  1. Makes a big difference review by Jeff Matzka (Stafford, VA) on 6/2/2015

    Installed this spring in my SP-01 Shadow and it made a world of difference in my double-action
    trigger pull. Much more smooth and manageable. Makes that first shot a lot easier to accomplish.

  2. It should have came in the original. review by Charley (Chagrin OH) on 6/2/2015

    I bought this spring for my wife's 2075 ( please note you will have to cut it down to fit) She went from a SA group of 3 inch to a 1 1/2 group. Also her DA action group went from 5 inch to 2 inch. I recommend it.

  3. A Key part in making your pistol stand with those costing $1000.00 and up. review by John Gaddis (Saint Petersburg, FL) on 6/2/2015

    This is a no brainer when it comes to Bang for Buck upgrades. If you carry you CZ for personal protection, you want to install this Spring. It is a extremely simple process so anyone can do this on their own at home. Pull your grips, holding the pistol butt downward to compress the main spring indenting the retaining cup into the back strap and use a tooth pick to push the retaining pin out. Swap springs and reverse the process. You now have one of the best DA/SA triggers on a lock stock pistol that anyone will find. If your trigger feels chunky or gritty and you do not feel you can strip your pistol, polish the parts needing it just shoot the gun and friction and use WILL clean the chunks and grit out....


    I added this spring just because of the other reviews and it feels like a different gun. The trigger feels more predictable and the DA feels like the original SA.

  5. mainspring review by Jack C Oskins (West Jordan, UT) on 6/2/2015

    I just installed this on my cz 40-P and love it. It's alot smoother, and lighter pull

  6. Drastic Improvement review by Ricky Tolbert (Bell Buckle, TN) on 6/2/2015

    This reduced the trigger pull a lot on both single and double action. Installation was pretty simple, and took only about 5 minutes.

  7. A great and easy upgrade. review by Eddie Gonzalez (Cathedral City, CA) on 6/2/2015

    I've changed out the main spring in 3 of my CZs with this one here and what a difference it has made in making them an even finer pistol. You'll be glad you did.

  8. THIS IS A MUST!!! review by Marco Moctezuma (Houston, TX) on 6/1/2015

    I saw all the reviews on here saying that this made a big difference, but never would I have believed just how much it is. This is a super easy install that anyone should be able to do and I recommend that you spend the few dollars on this. It is an immediate difference that has made my CZ-75B an even more enjoyable pistol to shoot.

  9. MASTERPIECE!!! review by julius estolano (Roxas City, Capiz) on 6/1/2015

    installed this one two days ago... it's unbelievably amazing...

  10. Essential Upgrade review by Randol Hooper (New Orleans, LA) on 6/1/2015

    Installed in about 5 minutes and the difference is night and day! The DA pull is lighter and actually smoother while the SA seems a good bit crisper and cleaner than with the factory spring. The difference is so great it's unbelievable; I can't imagine not having this spring!

  11. Great Upgrade review by James Prevost (Forest Grove, OR) on 6/1/2015

    The best upgrade i have bought so far made a huge difference in the trigger feel. I was able to stay on target much better after the install. Highly recommend this spring!!

  12. MUST HAVE UPGRADE review by Phillip Aranda (MERIDIAN, ID) on 6/1/2015

    This spring makes my cz75b so much more enjoyable to shoot! The trigger pull in DA/SA is SUPER crisp! Even cocking the hammer and pulling the slide back is smoother then the OEM factory 18lbs spring. A must have for any CZ owner.
