I never had any reason to doubt the toughness of my T3's magazine. It seemed sturdy enough. Considering that the plastic might actually make it more durable since it'll give a little and spring back, and in a pinch could be fixed with superglue. A bent or crushed metal magazine is useless.

Just make sure you don't lose the original magazine. Replacement T3 mags start at $65 and go up from there, and they pretty much have to be ordered.

The T3 is a good rifle. I had a T3 Lite in 300 WSM. It shot great, but it kicked like a mule on steroids, so I sold it.
