DA pull still stacking and not smooth after CGW parts and polishing.

[NerdAlert]

Hey guys,

I bought a CZ p07 and I followed the polishing instructions and adjusted the trigger bar spring according the sticky thread in the p07 section. I added the reduced power FP spring, plunger spring, TRS, HS-18 yellow hammer spring, yellow sear spring and a .220 roller. My original roller measured .212. The hammer was rubbing a bit on the left side of the frame so I mirror polished both sides of the hammer also. After this the pull was still heavy, gritty and stacks quite a bit. The only thing I didn?t do was the ?adhesive removal? on the decocker rod but mine doesn?t appear to have any. What am I missing, or am I just expecting too much from a polymer DA pull. I was hoping to get the DA something like Sig Legion series. Maybe I set my standards too high? Unless you guys have some tips for me I guess I?ll just shoot it as is and hope it breaks in smoother. I don?t mind the spongy SA and longer reset but I was hoping for better DA pull.

You need to reinstall your .212" roller as a start.  Going up .008" is to much of a jump and can lead to stacking in DA.  Try this first.

You are really expecting a huge improvement with a very minimum investment comparatively speaking. The Legion is a fairly custom production gun with a street price usually north of $1100.
The P-07 is selling south of $500 these days. Anyway do as schmeky advised and go from there. I'll add this if you want to really improve the gun try the CGW hammer as well. The spongy SA disappears and becomes smooth and crisp. You can also go down to the 15lb hammer spring which will help the DA pull but do as has been suggested first.

Don't know what your trigger pulls are (in lbs.)

My P07 (stock inside the frame/slide) is 3&1/4 lb. SA and about 8&1/2 lbs. DA.  My P09 (also stock) is about 1/4 lb. heavier in SA and DA than the P07.  But I hear some aren't as nice.

Don't give up.

Thanks I will try that. I?m aware I?m expecting a lot. I?ve spent about 3 hours working on it so far and my time isn?t free. I don?t have a trigger pull gauge. Weight isn?t as much of a concern to me as I?ve spent a lot of time with DA revolvers. I?m mainly concerned with smoothing out the stages, grit and stacking.

I tore into the pistol again last night and changed the roller, it did make it a little better. I also polished the flat part of the hammer where the sear slides in DA and the bottom flat part of the sear. After doing all that it still felt rough and...plasticky to me. After pulling the trigger very slowly and watching everything with the upper off I think I found the issue that?s bugging me. The trigger has quite a bit of side to side slop and rubs against the left side of the frame where it sticks through. If I?m careful and I keep it from touching the sides of the hole its in it feels MUCH better. I?m thinking maybe some shims unless there is another suggestion?

FWIW...

When I got my P-09 back from CGW, the SA was amazing but the DA was not as good as I expected.  I spoke with CGW and the encouraged me to shoot it a bit.  They made it clear if I was not happy they would do whatever I wanted to make it right.  Fast forward 1000 rounds - the DA is awesome.  It just took a bit to break-in.

Are you sure the hammer is no longer binding with the left side of the frame?

I had a P-07 that sounded just like yours, though mine also had the CGW hammer. Are you sure the hammer is no longer rubbing the plastic frame? Simply polishing the hammer was not enough for me, so I very lightly sanded the part of the frame the left side of hammer contacts until the hammer no longer touched that part during the firing sequence. This gave a smooth pull.

Yes I?m pretty sure it?s not binding at the hammer.

After similarly fully cajunizing (including hammer) my NIB P07 .40, I also still noted DA stacking though better than stock, but not seemingly as good as my P09 which had received the same treatment--but as others have said, after several hundred rounds (and dry firing) it got much much better--pretty happy with it now.

There are so many places the "P" series can experience drag internally, as some members have accurately pointed out.  Proper polishing, in our experience, does not guarantee a super smooth pistol out of the box.

What polishing does in the P series most of the time is significantly speed up the break in process.  And once the lock work quickly breaks in, the action can be excellent.

However, no 2 P series are alike, which can be frustrating for us.
