Some of the early SP2022 models had slide safeties, which are almost worthless IMO, as they're difficult to active/deactivate. Otherwise a great gun at a great price.
Based on that, you have yourself a rare item. As it is stated there, it's not a new model option and will be sold until inventory is gone.I'm in PA. I think this is what I got. http://lundestudio.com/SigProFAQ/IX/18.html
