I am looking to buy an new CCW, and Ive narrowed it down to these two... The Walther PPS in 40 cal, and the yet unreleased Springfield XDs in .45. They are very similar in size and I have never had a problem from either Walther or Springfield. One thing that comes to mind is the XDs is a brand new offering, and has yet to work any bugs out of it, and the Walther has been around for a bit. ??? Any thoughts?
