I ordered 3 of the mags. One for my brother and 2 for me. They came today and the shipping for 3 was the same as for 1.
Loading 1 in the barrel and 8 in the mag. My brother shot his 27 times and I shot 9 each.
They worked great. Never a bobble or a mislick. It was money well spent.
Thanks to SIGP220.45 for the information. Larry
