Review
easy to install and trigger is much better, very happy with this trigger upgrade kits. Very fast shipping!
3rd trigger kit I have gotten from here. Hard to argue with trigger pulls being what they should be out of the box for $30. Awesome install videos, that include polishing associates items making it that much better.
Good quality product, easy to install with the help of the videos and most of all great customer service! Will definitely buy again from M*CARBO!
Really smooths out and lightens the trigger pull. I have it in two of my pistols and I really like the kit.
Got this kit and the floating trigger pin. I chose not to install the reduced sear spring because with the new mainspring the single action trigger pull was already 4 lbs, my ideal for a regularly carried pistol. Installation, if you follow their directions and do it their way it is readily done. Would I buy the parts again? definitely yes.
Huge difference over the factory springs. Turned out with a great feel. I'll install this kit on my next CZ because you can't have too many CZs
This is the first one I have ever done and the install watching the how too video was not hard and easy to follow. Definitely an improvement over the factory trigger pull, especially the single action. Very happy with the product. Just check after the install that mags drop. The mag guide didn’t go into the slot at the bottom right when I put it back together and mags wouldn’t drop freely. Simple five minute fix and back in the competition. So far so good. I would recommend this to others.
Installed on a SP01 Tactical with the decocker with the fussy sear/decocker assembly. Couldn't have done it without the installation video, which was honest and realistic about the difficulty. Ended up having to do it twice, because the MCARBO supplied sear spring was out of spec (the short leg of the spring was a little too short to stay engaged on the sear. The coil diameter was a bit larger than factory, as well). Reinstalled the factory sear spring. The other springs still reduced the DA pull from over 12#+(!) to 10.5, and brought the SA down to 3.2#.
This kit is worth the time and money, and the instructional videos are excellent, however it does not deserve 5 stars. I almost gave it 3. There are 3 reasons: 1) While my DA and SA pull were reduced somewhat, it was significantly less than 50%. It was closer to 25% for each. I'm happy with the results, but don't claim 50% in the description unless you're sure it'll happen 2) We really need to know the spring weights--why is this not disclosed. 3) The replacement trigger pin should be an included part in this kit--it shouldn't be an option. Reusing the original pin MIGHT be ok, but if safety and reliability are concerns, EVERY customer should use the replacement pin when changing the springs. It's safer. And it's easier. And better. Overall I'm satisfied, and happy I made the switches. Take the time to polish parts while your gun is in pieces, and enjoy.
This was installed on a shadow 2, that already had a good SA trigger. In stock form, it had a 2.5lb wall with a break at 3.5lb. After the spring change, the wall was 1.5lb, with the break at 2.5lb. The DA pull, while lighter, is still too high to measure with my 8lb scale. A short pin for the sear cage greatly eased reinstalling the cage. A wooden qtip cut to length worked well. The spring kit is well worth the money.
Finally got the nerve up to perform surgery. Great video but uses the word "simple" much too often. I think that you do not know what that word means! Just kidding. I am very much a novice gunsmith and got the job done with a minimum of cussing and pausing and replaying the video maybe a few dozen times. I also got the free floating trigger pin and suggest that you mention that upgrade in the video. I got that part done and realized that I had reinstalled the OEM roll pin. Simple to drive that out with the new upgraded part however. I also had bought an increased power safety detent spring from another vendor and decided to swap that out at the same time since the sear cage was out. That was much more difficult than any of the other springs. Now have a stainless drop free magazine brake on order which should be a snap to install since I'm an old hand CZ surgeon now. Thanks for a great product and good instructions! Trigger operation feels great and I'm dying to get to the range!
Great quality, performance and price. Great improvement on my 75b.
Easy to install,very fast shipping and great product. I will be a return customer very soon.
Had a very choppy secondary trigger pull on my SP01 tryed polishing but just wasn't happy well over 12lbs installed trigger spring kit took me about 25min was very easy just went slow and was carefull, put gun back together was nice and light break could finally feel the fence til it for a test drive felt a bit gritty at wall so I held the exposed hamer with my hand and ran the trigger double action 100 times now runs flawless couldn't be happier highly recommend this kit if running a CZ at front sight academy or if you do competitve shooting.
spring kit quality are great. dimensions are exact as stock springs. easy to install without any hitch. polished a bit of the internals using 1000/2000 grit sand paper. had improved DA to 8 lbs and 3.75 lbs on SA. will test in the range to see how it pars out. customer service is great and fast shipping time. will order again
I am normally a bit leery about changing spring rates due to inducing reliability issues but MCARBO was recommended by trusted friend. These guys have done their homework! The product and the installation video is done exceptionally well. I was dissatisfied with the accuracy of my CZ75B due to the trigger prior to installation of the kit and in fact was considering selling the firearm or leaving it in the back of the safe. I am very pleased with its operation now and it will get to spend some time out of the safe! Accuracy is much improved and reliability has not been compromised.
