Dean, no, the hammer should only drop when it's fully cocked. It shouldn't drop when pulling the trigger in any other position. I just checked mine trying to pull the trigger with the hammer in all positions and it wouldn't let me pull the trigger unless it's fully cocked. I'd recommend contacting heritage arms at 229-210-2666 or you can also call 800-845-3776 Monday - Friday

No, that is not a normal function. You should definitely give Heritage Arms Customer Service a call at 229-210-2666 or 800-845-3776 or go to heritagemfg.com then click customer support.

Sounds like a malfunctioning hammer spring. Please contact Heritage Customer Service for their expert opinion at 229-210-2666 or 800-845-3776 or heritagemfg.com (click Support in the lower right corner). Cheers and stay safe!
