Ken I got one of the first to come out, I have put a Lightning strike striker in it and SIG replaced the magazine release button for me. It had rusted as I carry it 365! It turns out the cooks holster I had was allowing sweat to get onto the button and just stay there while I carried if hiking, working, what ever. I showed it to cooks and they made me a new holster on the spot. Great people, great holster. My gun has worked flawlessly except during the first 200 or so rounds it failed to lock back a couple of times and I don;t know why. I am considering buying another one, so may I ask "when did you buy yours"? thank you.
