Hi I have been searching for the 10 round 45 acp mags for my XD. The problem is, I am having a hard time telling the difference between the the large 10 round and the small 10 round mags online! I would like to purchase the smaller ones... Does anybody know the product code for these mags and/or know where I can buy them online? Without purchasing the wrong, larger mag. Thanks for your help in advance!
