This will be my very first CZ. I'll be getting mine next week and would like to upgrade the trigger set-up. It will be my primary CCW and range gun, I would like the DA/SA pull lighten up, about 5-7lbs on DA & 2.5-3lbs on SA. Are there any parts upgrade available online. And what are those parts, any inputs will be great? TIA!:)

Wow, I didn't even look at your country of origin. Sorry. I'm not sure if czcustom can export parts but they're gtg. To be honest, since it's a carry gun i'd keep it stock.

I've read that replacing the main spring and hammer would lighten up the trigger pull and just even with lots of firing and dry fire the stock trigger would just lighten up, thanks!

I put a 13lbs hammer spring in my SP01. It made a big difference in both the DA and SA pull. The gun is other wise stock.

Where can I get those 13lb main spring? I've only seen the 15lb spring at czcustom, thanks!

Fire it a lot. My CZ P-01 lightened up a lot since I first got it new. My wife wouldn't even shoot it, now she shoots it like a champ. There is now over 2000 rnds on it and keeps getting better and better.

CZ customs sells 13# mainsprings (at least as of right now) just installed one today. Otherwise, unless you want the weapon to go to a gunsmith, I'd say a competition SA/DA hammer and the mainspring are your best bets

check out this youtube video for info on CZ upgrades:

I got light strikes with a 13lb hammer spring. I use the 15.

the light strike problem depends somewhat on the ammo you shoot....buying a few springs (at 13 and 15) and testing em out is a good idea...they are only like 5$ a piece...

GT, how's the trigger pull of the Tactical compared to a Shadow, considering the mainspring and recoil spring is already changed to a lighter one/ Thanks!

Check out CZ forum, they have some good tutorials, and the CZ custom web site, for the parts. It is not to hard, you will need some punches and small files. It is mostly swapping parts. One of the tutorials advises putting the gun in a clear plastic bag before knocking the pins out, I thought they were kidding. They are not, there are a lot of little parts that go flying all over, be careful.

I got an SPO1, and installed the SA hammer and straight trigger with over/under travel adjustment, and removed firing pin block, lifter and spring. The trigger is tremendous, light with short reset. I only use it for competition though, as it is very lite. And I modified it to much for production in uspsa, but it is great for "outlaw 3 gun" with no major/minor for pistol.

A much easier mod is to use a reduced power main spring, a fairly easy part swap. You can also use an abrasive whiting toothpaste , mixed with some oil, applied to the parts that move against each other when pulling the trigger, than safely dry fire it alot, this will speed up break in and smooth things up a bit. Than of course clean the mild abrasive out, and test fire "alot", to make sure you will not get light strikes.

I also used the reduced power main spring and have about 500 rounds through the gun with out issue.

good luck shoot safe

GunFrog, a friend also suggested the whitening toothpaste w/baking soda technique to smooth out the internals:) My question is do I have to disassemble the parts totally, or just spread the paste on the moving parts? Thanks!

I wouldn't use the toothpaste method unless you plan to completely disassemble the gun afterwards and scrub every nook and cranny to get it out.

I changed my mainspring to a 13 pound version and stoned the sear engagement surfaces. In retrospect, I should have ordered a competition hammer and sear.

My incoming Australian model Shadow will have the 13lb main spring, 11lb recoil spring and competition hammer, will post pics soon
