Well, I beg to differ about the springs. I know others have had success, but I had the springs in my first set of mags and it only helped a little. I was having 1-2 jams per mag instead of 3-4. I will be trying to smooth the inner and outer curves some how and doing a bit of tapping with the ole hammer. I know they are the only company building them right now but like I said that being the case they should be making sure they are 100% before they go out and charging a premium for them. Maybe I will suggest they offer such a service. $20 for a crap shoot or $40 for a guaranteed/tested version.
If you look at the spine of the mags there seem to be a lot of wrinkles in between the spot welds. Obviously if that's wrinkled on the inside it could affect how the follower moves, regardless of what springs you have in it.
