I saw one done like this which broke at the screw location. I used to use a screw as a locator more than anything else when I was changing or re-attaching handles. The broken one I saw used a too large screw in a poor location.
I think the option which is best by far is to tig weld the handle to the bolt body. Second best is simply a good silver solder (silver brazed) joint. Those Remington handles which come adrift are those where the joint was improperly soldered from the factory. Regards, Bill
