CZ P07 / CZ P09 Trigger Spring Kit

I recently purchased the spring kit for my CZ P-07, the installation and polishing video were spot on, easy to understand and easy to see where the parts went. The trigger pull weight went way down, on my manual Wheeler weight measure the double action pull was off the scale, probably 10-12 lbs., the single action pull was about 5 lbs. After your kit was installed the pull weights went down to 7 lbs. and 3 lbs. respectfully. I love it…

I had an issue at the range though with several failures to fire. Was using good ammo, checked all the standard issues, firing pin cavity, and cleaned spring and pin well, but 2-4 rounds from almost every magazine had light strikes. I even replaced factory springs in the slide with no effect. I saw someone else mentioned an extended firing pin from Cajun Gun Works. Their part #61050 Extended Firing Pin, its currently $25.00 They say with the lighter springs and hammer spring, you may need this for reliable ignition. This did the trick, after installing this I have had 0 issues. I love the end results......would have been a perfect "5" stars if Mcarbo sold an extended firing pin

 

I watched the installation video a number of times. I have done spring kits before and was familiar with how it's done in general. I only had trouble with reinstalling the decocker. I found that the cam that lifts the sear had shifted, probably because I pulled it too hard when removing. After pressing it back into place everything worked perfectly. I chose not to do the full polish, just lightly buffed down the sear and hammer and the trigger bar. At the range the reduced double action pull is greatly improved and the single stage is wonderful. Very happy with the results. For the price its a great value over other options.

3/14/24 CZ P-07 -- Did both spring kit and polishing kit. I followed the great how to video and did not encounter any issues. Pre-install trigger weight. D/A was way over the max 8 Lb. on my scale Est. to be >11 Lb. S/A 4.75 Lb. After install. D/A 7.5 Lb. Avg. S/A 3.25 Lb.# Avg. Polishing made the pull very smooth. I went to the range with 5 brands of ammo, Federal, Remington, PMC, Norma & Seller & Bellot (S&B). I did encounter 4 failures to detonate (light primer strikes) on the S&B 124 gr. Ammo out of 100 rounds. S&B were the only brands that had this issue although light strikes were visible on all other brands cases. I purchased and installed an extended firing pin with included reduced F/P spring from Cajun Gun Works. Back to the range with new extended Firing Pin installed. 150 rounds of S&B later, no more failures. After about. 500 total rounds of the various brands, the only issues were with S&B, and this appears to be fixed with the extended firing pin (noticeable deeper dent on the primers). It seems that S&B has harder primers then the other brands I fired. All in all, I am very pleased with the M-Carbo parts and polishing kit., and with the addition the of extended firing pin I now have a great shooting & smooth feeling CZ P-07.

After couple hundreds of shots my trigger just stop returning. I saw similar problems in reviews and suggestion to stay with original trigger return spring. But I just go back to original spring set. Because it is my primer gun and I can't risk on quality like this. Also red lot of reviews about the light strikes before installing M carbo kit to my gun. But decided to give a shot. Unfortunately had just big disappointment.

Awesome product, after polishing and replacing the springs with the Mcarbo kit. It brought the double action to 7lbs and single action to an average 2.8lbs with reliability .

 

This trigger spring set will not work on a P 07 Omega. The trigger spring is to weak to reset the trigger. Wasn't mentioned in the weapon details information. Use the original trigger spring to partially lighten double action trigger pull.

Great quality and easy to install watching MCARBO installation video. Reduced trigger pull as advertised. Definitely recommend this product!

Installed the spring kit last week, followed u-tube instructions to the letter. Overall, I noticed DA and SA trigger pull noticeably decreased. However, after 10-20 shots the trigger stopped reliably resetting. Double checked install, everything was correct, so I put the OEM trigger spring back in, and trigger resets perfectly again. That said, when I gauged the trigger, I’m at 9.5lbs on DA and 3.8lbs on SA. This is a reduction of about 1lb for DA and SA. Because of the recommendation polishing, the trigger is notably smoother now. I suspect if the trigger return spring worked properly, just by feel, I suspect I would have had another pound of reduction on DA, and maybe a couple more ounces in SA.
