I have a Bersa Thunder .380 After shooting 150 rounds it failed to fire. The hammer was cocked, but there was no tension on the trigger, pull the trigger and nothing happened. Dropped the mag a couple times and it reset and fired one round then the same thing happened. Even after resetting into DA no tension on the trigger. removed the grip and checked the springs- everything looked good. Even when it resets and drops the hammer, the trigger will not reset forward.
