In my CZ 75 DB, I have replaced the main spring hammer with a 13 lb and put in extended firing pin and spring, both from CZ Custom.The double action still feels very heavy.What else can I do?

You can try an even lighter mainspring, but you may well have trouble with mis-fires.

If you try another spring be aware that you'll need to shoot AT LEAST 100 rounds OF THE AMMO YOU INTEND TO USE IN IT, to do a reliability verification.

Another option is to send it to a CZ specialty pistolsmith and have it custom tuned.
There's only so much you can do so you may have to live with it.

On the CZ-USA web site is a link to their pistolsmithing source. I'd talk to them.
