I will say after using the Springer TS pads for only one match, the retention with the set screw is a terrible design. The screw fits so tightly to the lip of the mag body that the screw threads engage the mag body and it takes zero effort to round out the hex socket of the set screw. They came with extra set screws, I should've known that was a bad sign from the start. I replaced two set screws from the word "go", installing the pads and backing out the screws to retain the pad was enough to round out the socket. There is a thread locking compound on the threads from the manufacturer, and I don't think this helps the stripping issue. The hex driver they send with the pads is next to useless, it rounds off promptly as well, within the first couple uses installing the pads.
If I were to do it again, I'd go with the CZCs. I sat down to clean mags after a USPSA this weekend and had one set screw that rounded out before I could get it recessed far enough to remove the pad. Now I've got a mag with a basepad that won't come off. Sweet.
