I have a beautiful new CZ 75 SP 01 Canadian Model (smiling cheek to cheek). I put 150 rounds through it today and it is a great gun. The kit comes with 2 additional recoil springs (11 and 13 lbs) I believe. 2 addition main springs (13 and 16 lbs) and 1 firing pin spring.

My question is which of these springs would I match with one another to reduce the trigger weight as much as I can while shooting factory loads? I don't want the slide hitting to hard.

I will be putting at least a few hundred more rounds through it in the next week or so to break it in before I change anything but I am trying to educate myself now and start planning for the near future.

This is the first new pistol I have ever bought so I figured about 1000 rounds for a good break in period. Any opinions on this?

TY all in advance for any intelligent responses. I do love to learn from others valuable experience. I look forward to your responses.

Myself, I run the factory recoil spring in my SP01 shadow and the 15lb main spring, which I do believe is lighter weight than oem. I do have the competition hammer upgrade on my shadow. I run that for pistol longevity and reliability. Have not had a failure to eject or a light strike yet and gone through 2000+ rds.
 
I did a trigger pull on my CZ Canadian edition and it came in at 3.5 lbs.How much lighter do you want to go?I actually think my trigger is too easy to pull.The gun shoots great right out of the box with the springs that are in it.Mind you it would be nice to know what poundage the other springs are since there is no color on them to distinguish the difference.One thing I did purchase is a trigger return spring (newer model) just in case the OEM spring breaks.I also changed the slide stop to an original model (bit shorter)only because I found the safety was interfering with the longer slidestop...other than that great gun,scary accurate.
 
13 lb recoil and 15 lb mainspring seem to give us good results on the 2 cz75 spo1 shadows we run.

The more we shoot them the smoother the trigger pull seems to get. Double action is just over 5 lbs
 
I have the CZ Shadow SP-01 and I installed the 13 pound main spring and 13 pound recoil spring, as well as a competition hammer. The pistol shoots fantastic, the slide is easier to operate, and the trigger is both smoother and lighter. No failures with factory US ammo, just a great gun. Gunsmith Joe Dlask of Dlask Arms recommended the 13 pound recoil spring because it's light enough to make the slide easier to operate in a hurry and if you ever want to shoot a bit of +P ammunition it'll handle it, whereas going with the 11 pound recoil spring makes the pistol a standard load 9mm shooter only. The 17/18 pound stock recoil springs that CZ puts in their pistols are designed for long life with NATO military +P+ ammo. The 13 pound main spring is all you need for modern American primers, the 16 pound stock main spring is there in case the pistol was shooting harder primed Euro ammo...I've had no failures with my 13 pound spring, and Joe said I wouldn't. His final recommendation was the competition hammer, and it just feels smoother and works perfectly with the lighter springs. So I'll pass on 13 lb. main, 13 lb. recoil, and competition hammer. :)
 
Cajun gun works is a great place to order springs from too, but you have to use a USA mailbox to get them
 
The springs CZ custom sells are Wolfe springs, but the ones Cajun sells are ones he has made for him. His main springs are much better in my opinion.
 
I went with a 13# mainspring from which I clipped 2 coils, and an extended firing pin. Single action breaks at 2.75 lbs.
