These magazines perform very well in my CK Arms 9mm. They hold 21 9 mm rounds. They are easy to disassemble and clean.

I had heard nothing but great things about these magazines, so I ordered 3 of them. When I receive the mags everything seemed OK until I started shooting with them and kept having feeding issues with the magazines I took them to my local gun Smith who said they were out of spec we fix them and didn't have issues after that. But the fact that you spend a $130 per mag they should have 0 issues coming right out of the packaging I emailed mbx And their response Was after I told them what it happen that they have thousands of shooters that experience no issues right out of the packaging And just left it at that. I never got any further responses about the issue past the initial email would never and will never recommend these to anyone.
