How do I reduce DA pull on my P-01?

[igolfat8]

I just did a thorough polish, thorough clean and lube on my brand new P-01 Omega following the excellent tutorials in the gunsmithing section. Replaced the hammer spring, with the blue one from CGW, extended FP and lighter FP spring, lighter safety plunger spring. Before the work the DA pull maxed out my digital gauge so it was somewhere way over 14 lbs and the SA was 6. After all the work my DA is 9.5 and SA is 3.25. DA is very smooth now with no stacking or gritty feel. The DA is acceptable but I would still like to reduce the DA pull significantly more. Any suggestions?

1. CGW 75220 Double Action Roller for Omega
2. CGW Reduced Power Trigger Return Spring

I did not measured DA weight, but it's about half of original pull now.

I am unclear if this applys to the Omegas as much as it dose to the CZ P Series poly framed pistols but inspecting the trigger bar to see if it is rubbing against the inside of the frame may be worth while. Flattening and then polishing the outside of the trigger bar made a significant difference in my P-09's DA pull.

You may be right. With Omega it's even easier and faster to polish the outside the trigger bar (it's only on one side of the frame)


And I would also polish the inside of the frame where trigger bar slides on. It's alu, so sand paper 1400 or 2000 does the job.

I did replace the trigger return spring and forgot to mention that. I stoned and polished the back of the trigger bar (frame side) as well as the adjacent side of the frame.  I buffed the DA roller but did not replace it. I will make that my next component to replace. Thanks for the tips guys.

This was my first adventure into a complete tear down and shade tree trigger job. It was a bit intimidating but YouTube got me through it and got it all back together and FUNCTIONAL, the first time! Phew... All totaled, it was about a 5 hour job. It should go better next time.

I did notice that the ALL of the parts were slathered in grease, which I found to be odd, including the firing pin and channel. In my experience, the trigger group tends to get pretty dirty from burnt powder residue and grease is a magnet for that airborne carbon particulate. I used a wet/dry lube (Strike Hold) on mine when I reassembled. What are you thoughts on lube in the trigger / fire control group?

U R Welcome

I was thinking about the same doing my P-01, but found info somewhere that whatever you do with original roller it would not be the same as CGW DA roller.

First time is always slow when you are not confident about the job. My first full cleaning, polishing and CGW parts setup took me over 2 hrs (but I spent whole day to watch YouTube instructions)

I'm not a fan of using A LOT of grease.. just a film spread with finger. Firing pin channel MUST run dry. Of course after using cleaning solvent it's a good idea to wipe everything out with oil, but firing pin and channel should be dry before reassembly.
A don't put a lot of lube inside the pistol. I wipe everything out with patch (drop or two of oil on it), or cotton swab (hard reached areas). Don't be crazy with oil.
If you find any oil leaks outside the gun after testing (rack without magazine, cock and release hammer, press trigger - all several times) that means you put it too much.

I installed the CGW roller today and it alone reduced the DA pull a whopping 2 lb from 9-1/2# to 7-1/2#. The SA pull went down to 2#10 oz from 3-1/4#. The roller alone smoothed out the DA pull extremely well. My OEM roller measures .215” OD and the new roller measures .220” OD so I am not sure if the .005” in total diameter increase changed the timing or not but the bottom line is I am VERY happy with the final results! A big thank you to CGW parts.

That's the CGW Magic

P-01 Omega  - I ordered the ultra light kit and reduced power trigger return spring from CGW, and just finished up putting it all back together.  Prior to part replacement, I polished the following: contact points of the trigger bar and frame, rear of trigger bar, outside of DA roller and sear pin where it slides into roller, the hammer strut, the FPB plunger and contact point of the FPB lifter.  I used 1000, then 3000, then 5000 grit sandpaper from a 3M headlight restoration kit.  DA pull is noticeably lighter, but without a gauge, I cannot confirm it is 50% lighter with the 13# mainspring.  I also lightly polished the face of the sear, and noticed a bit less resistance on SA pull.  It's still a longer SA pull than I would prefer, but I will need the P-series hammer and heavier sear spring to achieve that goal.  I knew this would be the case prior to replacing the other parts.

I am pleased with the results so far.  Hopefully I will get to shoot it soon.   Using the pencil test for firing pin action, it launched the pencil a bit farther than before the part replacements.

Got the CZ bug not that long ago (have 4 now),Shoot speed steel with 3 of them,dbl action does seem to lighten up some(if I pay attention to it),but honestly if you don't focus on the pull you really don't feel it.If I focus on my target and first move,its smooth and light.
