Jeremy, the '75 catalog shows the strut present on the C mag; '76 thru '78 catalogs shows it on the B and C mags; None show it on the A mag. I only have the hard plastic grips. If you are interested in a RH #1 grip, I can ship you one. Just reimburse me $10 for priority mail with ins and delivery confirmation. Also, does your B mag have the plastic bear button, which should be from late 72 and newer? Let me know about the grip. thanks
