Not yet, but I hope to soon. I have a Springfield Operator that I bought new and have only put 300 rounds through it. I have had some FTE issues to the point that the slide crushes the spent casing against the front of the breech. It usually happens to the last round in the mag. I don't think it's the magazines because I'm using the factory mags and I bought a Kimber Kim-pro Tac-mag I think that its just the recoil spring that needs to be broken in a little bit more, which means Im going to have to go shooting more....dang!
So like I said I wouldn't trust mine just yet, but I'm looking forward to the day when I can.
