I purchased one of the extended barrel versions of the P-07 Duty, came with Tritium sights and came set up for S/A, cocked-n-locked.  No parts to switch over to DA.  


After a few years, and 3k+ rounds, I've decided I want to switch it over to DA/SA.  




What parts specifically do I need to purchase to switch to the decocker?  How's the assembly?  


 

It should be DA/SA even with the thumb safeties installed.  If not, there's an issue that should be fixed.

As to the installation of the decockers, you need the left and right side decocking levers and the spring.  That spring is used for the decockers but removed for using the safeties.

You can get the decocking levers and spring from CZ USA or CZ Custom (not sure about CZ Custom, but most likely they carry those parts.)

Do you have the owner's manual?

The say that spring is a real bear to get back in the right spot.

It is da/as, but only has the safety, no decocker.
