CZ 75B CGW Conversion
Just picked up my CZ 75B yesterday and did the CGW parts conversion. Went out and shot it today and I am absolutely impressed!
First off, the fit and finish of this particular handgun was rather good out of the box. The trigger wasn't too bad either, but only so much can be expected out of a DA/SA firearm.
To do the conversion, I replaced the trigger, hammer, and sear with a CZC Tactical Sport straight trigger, CGW race hammer and adjustable sear kit. I also removed the firing pin block and the firing pin block lifter, which significantly reduced the reset of the trigger. I also removed the disconnector which made it single action only.
Just like all my other CZ's, this one is no different. The recoil is easy to manage and light with great reliability with no failures during my range session. I find that my CZ's often have a 6 o'clock hold and from my target, you can see that with the grouping with it shooting a little on the high side. I may get a taller sight post in the future to make the sight picture a more of a combat hold.

The difficulty of the conversion was definitely more hard than working on say a striker fire pistol like an M&P. Because the older trigger system of the 75 series CZ's, they have more parts thus making it more difficult to work on than the CZ P-07 which I have ample experience with.
With that aside, the hardest part was definitely managing the springs in the trigger and setting it in the proper position to drive the trigger pin into the frame. Even so, with slave pins, it made the job that is manageable, but at times, I wish I had a third hand.
Aside from that issue, removing the pins in the hammer for the hammer strut and the disconnector were extremely difficult. I purchased the starter punch from CGW and the tip of even that started to peen from the pressure required to remove the pin. At the end of the day, I was only able to push the hammer strut pin far enough to remove the strut, but I completely bent a steel punch trying to remove the hammer strut pin, so I just gave up on the pin and used the trigger slave pin as a replacement pin for the hammer strut on the new hammer. The trigger slave pin fit inside the hammer strut punch hole with finger pressure, but since this part of the hammer is enclosed in the frame, there is no risk of the pin falling out. This is actually how the CZ P-07's are as well, as it is much easier to remove the pins in the hammer on their polymer models.
The new trigger is really nice and I like the flat trigger a lot. Aside from looking pretty sweet in the frame, it functions rather well. I purchased the CZC Tactical Sport trigger because CGW were out of their triggers with pre and post travel. The trigger adjustments are awesome and really allows you to remove the take up and the post travel of the trigger. With the FPB and the FPB lifter removed, the trigger movement is decreased to 2mm, and the reset is right where the trigger actually rests. To fill the space that is left with the FPB lifter removed, CGW offers a spacer that costs only $1.50.
With the adjustable sear, it allows the manual safety to work properly with the new hammer and trigger system. Opposed to what most people think the adjustable sear is, it isn't to adjust the breaking point, but solely to ensure the safety works. I find this screw actually is loosely fitted into the sear and required a bit of lock-tie in order to not walk out. Even without an a seat that you can adjust the breaking point, the CGW seat is certainly great where it is set. It will rival any custom gun on its breaking point and performance.
With that said, the firearm was a lot easier to work on than originally expected. But after everything is said and done, the only thing I would have done differently was get pins for the hammer strut and disconnector if I was going to use it. I'll be sure to do that when I upgrade my P-01. For all the modifications, the end costs on top of the firearm was $249.
. Would send to CGW but it's cist prohibitive.
