I have one and I love it. I used to have a 915 (similar, but blued slide, alloy frame and non-ambidextrous safety) and I loved it, but I traded it as part of a Sig P-226 buy.
Anyway, I actually got mine from Summit on Gun Broker, too. Mine is from a run that has no magazine safety from the factory. I was very happy with the deal I got, even after paying for shipping and local FFL transfer fee.
