That is the good news. The bad news is the shipping cost ($10.21 to Texas) is more than the cost of the spring ($8.95).
By coincidence, I have a spring on order to be delivered on 3/6/2012.
I can't vouch that the spring is any different than those you had before that are unsuitable for the G20 mags. My only experience with the KSV MagEx spring is with the extension kit on G21 13-rd 45ACP mags and as a replacement spring for the inferior spring in a Korean-made 27-rd 45ACP mag (Victory brand).
