I considered the Grey Ghost Precision P320 slides and the Zaffiri Precision ZPS.3 slides, but the SIG SAUER offering ultimately won me over due to its factory-direct reliability and the inclusion of the X-Ray3 sights.
My first impression was excitement; it was a noticeable upgrade that promised to bring my P320 into the modern age.
