I haven't been paying too much attention lately,,, so sorry if there is a more recent thread to report range findings regarding the new magazine springs. I ordered two springs a couple of months ago based on positive experiences by some at this forum. Previously I experienced failure to eject problems approximately 5 - 10 % of the time, it didn't seem to matter which of my 4 magazines were used. After installing the new springs I've had 100% reliability from the two updated magazines. Each one has now been loaded up 12 times each with handloaded 124 gr Gold Dots which approximate the velocity of purchased ammo. I'm satisfied that this now solves my problems, especially because after disassembly I found that my recoil spring was quite a bit shorter than the new one I was about to replace it with.
It's now time to order new springs for the other two mags and more recoil springs. I think the 100 round replacement of the recoil spring should now be addressed. I still believe this is one heck of a partner for daily carry, but having the additional confidence of the recoil spring having a longer life would add to the warm fuzzy.
