Do the mags have stops on them? I was doing rapid reloads with my Eclipse with full size 8 round mags (normally takes short 7 rounders) and snapped the ejector pin right off.
I have X-Grip adapters on 2 CMC 8 rd. mags for my Officer size 1911, and factory adapters on my 2 Taurus 24/7 standard size 12's. It came with 1, and I bought another directly from Taurus.
