Wish i had seen this thread before i bought my pmags. I was able to find a reasonable source for Cmags on the net. https://www.44mag.com/product/308_10_magazine/cproducts unfortunately i have also found out that C-mag is out of business so what is out there is out there. I do hope these work well. or i will be contemplating that paper clip option mentioned above. depending on how things go i may have a story for this group but i hope it will have a good ending.
