Did you buy it new or used? Reason I ask is because if it's used, someone may have messed with the trigger or springs. Also, what one of the gunsmiths at T/C told me once was Pachmayr grips will weaken the mainspring to the point where the gun won't fire. I had bought a used Contender with Pachmayr grips that wouldn't fire. Had to send it to T/C for an overhaul, and they did an excellent job in record time. Might want to call 'em.
