The only link I have is via Facebook. I've long been a fan of CDM Gear and he is now expanding his Mossberg line with a metal safety which he himself has designed and produced. https://www.facebook.com/cdmgearfan...05794072/?type=2&theater¬if_t=video_reply# I think this called the "Delta Wave" safety and in the video it's mounted on the 930 SPX. He says he'll have other colors available at some point too and with an attractive or competitive MSRP. I'll see if it's something I can get a hold of when they become available so I can actually review it here.
