I've had my Shield 9mm a little over 3 years now. I put Talon Grips on it and an Apex trigger sear in it. I carry it dailyin an IWB holster. The Talon Grips still look like new. With 1,988 rounds through it, I've had no mechanical problems. I did have a couple of FTEs in the first 200 rounds, but since then its been perfect.
