I just installed the flat trigger short reset kit into my a01 which functioned 100% before.
(Disconnector, flat trigger,trigger spring) also the extended firing pin and spring, 10lb hammer spring.
The pistol works fine in Da/SA with the slide off. Put the slide on and hammer will not drop to fire. I take the slide off, barely push up on the sear where it meets the hammer, and the hammer comes forward. I don’t understand why it functions fine without the slide but not with the slide? Could it be the trigger bar springs? I would call CZC but it’s the weekend and I’ve called 3 times this past week leaving a voicemail with no return call back. If anyone has a recommendation it would be appreciated. Thanks
