Coming back to you a bit late on this, but I remembered this thread and returned to it.

Someone correct me, but leaving a spring compressed does not weaken it. Repeatedly compressing and releasing it does - a tiny bit. Just like you do no harm to a bolt action rifle leaving it closed with firing pin spring compressed.

Compressing a spring to beyond its elastic limit really weakens it. By that measure, forcing one extra round into your full mag will achieve a bit of your stated aim of making the spring easier on your fingers. I'd personally just take some emery board to those sharp mag lips.
