Is it possible to shorten the reset on 75B Omega?

[jabate01]

I have a 75B Omega with the CGW Omega kit installed. Is there any way to shorten the reset in the trigger even more? Also want to remove as much pre-travel as I can in Single Action. Is any of this possible or do I need to start over with a SP-01 or 75B SA?

Not to my knowledge, the CGW kit that you already have installed is the only reset reducing kit available for the 75B/O. I am less well versed on the Omegas than I am with the classic trigger system. Lets see if another forum member chimes in with any added information.


This is an interesting thread that may be worth taking a look at. While these modifications may not be a viable option for most folks, it dose go into great detail about what would be required and how the Omega system works.

Jabate01......can you provide any feedback on the omega kit?

[jabate01]

First off, thanks for the article.

As far as the Omega kit goes, I am happy with it. It was a good investment. Right now my goal is to turn my 75B/O into a SA race gun. The Omega Kit helped out in all around performance, it didn't shorten the reset as much as I would have liked. My plan is to shorten the reset more and add a flat SA trigger and mag well. The 75B/O is a great budget friendly, entry level gun for competition. The Omega kit is a great next step when your ready to get a little more performance out of it. Basically I'm trying to build something like a Tactical Sport Orange with what I have. Any help Is greatly appreciated.

I may be wrong, but I thought the Omegas couldn?t use the SA only trigger?

My guess:  CGW and or CZC will likely "hand work" a specific pistol  to the tightest possible action specs that you request.
My second guess is that the pistol won't stay all that economically practical if guess #1 is correct.

Glad this thread came up. 

The Omega lock work is very simple, but is not very precise.  Nothing wrong with this on a service pistol.  The trigger bar is stamped from sheet metal and can vary quite a bit in overall length.  We keep some factory trigger bars on hand and sometimes and swap them to improve a shop built Omegas performance on occasion.  Sometimes this swap helps, sometimes it does not.

The timing is also different from the polymer P/07/09's to the metal framed Omegas, so the parts have to be a compromise (of sorts) to all allow performance parts to drop in across a wide spectrum of CZ Omega models.

Also keep in mind there simply must be a minimum of 3 mm pre-travel in SA to allow the firing pin block to lift sufficiently to make the ignition system 100% reliable.  This is the main factor above all else in the single action short reset.  This applies to the standard lock work models as well.

The Omega is a service weapon, and to make it into a full boogie race gun is not something is was designed to do.  1SOW is correct on the single action conversion, there is a very good reason no one makes a trigger for this, since the liability of converting a decocker to a SAO is a law suit waiting to happen.
