Hello gang.
I've bought mag carriers from Magholder.com for every carry pistol I have. Their product is excellent, incredibly comfortable to carry, virtually disappears under any type of clothing. The company has an excellent customer service and they're very personable.
I'm buying one for my Sig P320 so I can easily carry that spare mag. They have some videos on YouTube and on their website that you ought to check out.
I also got a hold of a discount code. Normally the mag pouch is $25 but with this discount code it comes down to $19 and change. Shipping is cheap and fast. Check them out.
