I've heard this in the past few months, but the $200 for 50 mags from CDNN is just soooo tempting. So while on their site today ordering some Glock magazines, I added a thermold 20 round mag in my cart. Gonna take it to the range a few times and test it out. If it's gtg, ill buy the 50 pack, if it doesn't, I only wasted $4.96 on the one mag.
