i ordered these because KCI mags i had previously bought required a good deal of fitment to function in my MAC mp5k, so i figured that i'd spend an extra $10 per mag to get these mags from the same manufacturer, expecting them to function without modification or fitment. however, when i received these mags, they were noticeably different than the 2 mags that came with my MAC mp5k (the bolt clearance at the rear of the mag is smaller, and so it will not strip rounds from the mag without modification to open this area up)

These are well made. They do require a break in period going in and out of the as they fit tight. Avoid the ones with the bolt hold open button, they are for the IX 9mm.

A real good mag at a fair price. Wish they would put them on sale!

product met my expectations and arrived in a timely manor

Just as they advertised with fast shipping

Fit and feeds flawless

The magazines well built and look durable. I can't wait to get them to the range. The company was excellent on shipping and handling.

Great quality magazines that came with my one X would like to have extras. Wish they sold them in a 10 round because of my state.

Customer service is on point. I swear they are the Amazon prime of the gun world. Shipping is always super fast, product quality always about the basic standard .
