I bought Ed Brown mags first, they had a trade-up program for the Pez Dispensers that come with the firearm. They did seem better-made and definitely had a stronger spring. But I kept hearing about WC and so I took the leap of faith and sold the Ed Browns on eBay and ordered two WCs. OhMyGoodnessSakies as my wife says, just the feel of the construction on the WC mags is better by a big margin. I grabbed two more during the Black Friday sale. Yes I only have 4 mags right now, but I really like the these WC's. Granted, I'm not a longtime experienced shooter, but just on build quality and the strength of the spring and the way it feels when I load 'em, if the stock mags were a 1 then the Ed Brown would be a 4 and the WC a 10. Just my $.02... after tax and 401K deduction.
