I bought it online, sent it back to the seller for repairs and it arrived back fixed. Removing the grips and taking a look inside seems to suggest a new spring, but I don't know for sure as the seller did not say what he had to do to get everything running properly. 100 rounds through it with no issues. I was surprised how accurate it was at short range (10 yards) with very tight groups and the trigger was better than I expected for a DA only.
