It appears from the many reports I've seen that the springs fail (bend) DURING MAGAZINE LOADING, but NOT while firing. Have I missed reports of failures to feed due to the spring having folded while the gun is being shot?

S&W is providing new springs after I called 'em about my failure experience, but I also have some Wolff springs on order which should be here in a few days. The Shield has been completely reliable over probably 700 rounds now, except for this one spring failure. If the spring failures do not occur during shooting, I'll be inclined to put the new Wolff springs in the mags and return the Shield to its place as my daily carry piece.

But if I've missed reports of springs folding up while the gun is being shot, I may just leave the Walther PPS in the daily carry holster, and give some additional thought about how to get comfortable with the Shield again.
