Hello. New member here with a brand new CZ 75BD with 75 rounds through it. The pistol shot fine at the range the other day. Yesterday I did a little dry fire practice (<10 dry fires) and the hammer stopped completely droppin in SA mode. I pull the trigger and the hammer will drop to the decock position a few seconds later. Manually fully cocking the pistol has the same results. When fully cocked, the decocker works most of the time but occasionally will not function. DA mode works fine. My apologies if I am not using correct terminology. Any help is much appreciated!
