It's been awhile, but there was a thread on this some time ago with some good pictures.
There's only 3 parts to the mag release. There's the button, then a hinged piece, then a bent, flat spring. The area of the frame where the hinge sits is put under stress when you eject a full mag. Check that area for wear. If it looks good and you have all your pieces, then you'll be able to put it back together. IIRC, the other two parts just drop in, and then sliding the spring home keeps the other parts in place. You'll probably need some needlenose pliers or such to get the spring back in.
