I'm having a strange problem with CZ 82 pistol right now and thought someone may have some idea how to fix it. The basic problem is when holding the pistol in the firing position with the hammer back and the trigger is pulled, apparently the sear only partially releases the hammer and the hammer does not completely fall. However, if you hold the pistol on its side, at about a 90 degree angle in either direction, it will fire. Strange, but that is the problem. Thanks in advance for any help.
