Not sure why so many folks do not like Tapco, I have a few 30 and a couple of 20's. Never had a problem with them. Just as reliable as my steel mags, and lighter also. I am sure you could break 1 if you tried hard enough, but they seem durable to me. Different strokes for different folks, I guess. I do not think they deserve to be called crap though.
