I avoid totally plastic magazines and only use 10/22 magazines with the steel lips. Specifically I buy Butler Creek Steel Lips 25 round magazines when I want hi-cap mags. The best ones are made by Tactical Innovations, but they are also the most expensive. I find that Butler Creek work flawlessly for less cost.
