I think it looks good. It looks very similar to the recoil spring used stock in the Taurus Millenium Pro. When an unsolicited recommendation comes along by a legit customer who has nothing to gain, I tend to pay attention. After I get a set of night sights for my glock, this spring be the next upgrade on the list.
Unlike the hardcore folks, I chose a glock because of all of the accessories available. I just put a 3.5lb trigger connector in mine and I am amazed at how much better I shoot with it.
BTW: I'm considering the
Truglo TFO Tritium/Fiber Optic sights.
What other changes have you done to your glock?
