This is for all you Sig owners and lovers. I plan to add to my handgun collection (XDM and an XDS) either a Sig Sauer P226 Enhanced Elite or Elite Dark. The little bit of information out there states the difference between the two are the grips and the adjustable night sights. Anyone familiar with these two pistols? Are there any other difference between the two guns? I'm looking to add this to my collection in about a month or so. Your responses are greatly appreciated!
