I have owned my Henry Big Boy- .45Colt- for about a year. I have more then 2 K rounds through it. Last time out it suddenly stopped firing. I checked the rounds, the primers were not dented. Took the bolt out and saw the firing pin was broken. Took the rifle to my local gun dealer (he sold it to me). He contacted Henry, they sent a new pin. Dealer put it in-no charge. Hats off to Henry. I really enjoy shooting this rifle.
