Welcome to the forum and please continue to share your likes with us. Speaking of the M220 Trap guns....Savage did make one. I have a 12, 16, and 20, and was out bid for a .410. I have not seen a 28 gauge Trap model. I have purchased a vented rib from Numrich that I plan on having my gunsmith install on a mismatched M220, 20 gauge that I have.
