Friends, I just purchased a mint condition sig sauer p220-1 pistol in .45 at an estate sale. It sat in a safe since it was purchased back in 1992. It cames with all of the original receipts. I took it our for a shoot and it worked great until about round 75 where I experienced some jamming from one of the clips. I think that these are the original factory clips. They look allot like the old design. can someone recommend some reliable clips, or know of a resource for factory clips without costing an arm and a leg? I hear of a brand called ACT-MAG? Are these any good? Also, regarding such an old pistol that had been unfired for so long, could I may be experiencing just some break-in activity that may not be clip related.
