Kevin, Call Al Marcucci at Savage Magneto 510-782-7081, PDT. He doesn't make them, but has a supplier who knows his 'stuff.' I had him supply a harness for the 150 Franklin with Eisemann mags. It fit nicely without a lot of extra length that needs to be secured. Al's address is: 2415 Radley CT. Suite 7 Hayward, CA.94544. Ask what colors are available. Dan
