Even after having a 52 for a while, I still only have the two original mags for it. I am finally going to get more. Other than surplus mags, I have only seen new after market Triple K mags for it, and would like to know how good the Triple K's are in terms of feeding and reliability. Any one having used them, good or bad experiences? If good I may try them, if bad, I stick with the buying original ones.
