thanks for the pic above. I filed and filed the disconnector exactly where u show and still could not get the trigger to release after the slide was put back on. Yes the safety was in the off position. I reinstalled the factory hammer and disconnector with the hammer spring, trigger spring and sear spring from Cajun Gun Works and everything seems to work great. Still waiting on the extended firing pin as they sent me the SP01 firing pin. I have not shot it yet, but the feel and function of the DA and SA is great. The only difference I can tell with only changing the springs and using the stock hammer and disconnector is that the safety will not go ON if there is a live round in the chamber and the hammer is all the way down. So for us Production shooters the gun will operate just like Factory. The safety works with the hammer all the way back or in SA mode like a 1911. I think this is a good feature for Production as the gun is exactly the same at the CZ Factory intended except for lighter springs that I have installed.
The Cajun Gun Works Competition kit allows for the safety to be ON with the hammer all the way down on a live chamber for use in DA. SA of course you can put the safety on as well. It's different and might be safer for home defense. I think I prefer my set up with the safety off in DA mode for competition just like a Beretta.
