One of my Fox hammers broke....

I'm a wood guy; completely ignorant of metal stuff. Heck, I've never even had a mower deck welded! I'd like to hear opinions please, on a welding repair or whether it's very highly advisable to locate a replacement instead.
Funny, but I had just completed a 100 bird sporting clays tournament without a hint of trouble.....even broke the final pair! Back at the clubhouse, I picked it up from the rack, broke it open and carried it to the truck. Went to close the gun to remove the forend and break it down and couldn't close it...the piece was laying in the action.
