I see these comparisons between steel mags and Tapco mags, but honestly I think they're for different things. Steel mags are great if your gun holds them tight. Mine, and many others' don't, though. That's why I like Tapco. They're thick, so they tend to fit my AK better. I wouldn't trust them for a SHTF thing, if that means anything to you. I'd rather deal with the annoying wobble but have a great steel magazine. But for the range, I love them. Nice, solid mags.
Plus at $9 a piece at my local fun shop, I pick one up almost every time I'm in there and they have 'em.
