I have a similar question.
I lost the entire trigger assembly to my m-1 garand, then bought a new trigger assembly at a gun show. Mine is a springfield, but the trigger assembly I purchased was apparently made by beretta. The fellow I bought it from told me they were interchangeable. Well, they are not!!!
If I just purchased a new housing, and then reassembled the whole housing, would this then fit my M-1?
