The action on the SXP is crazy slick. I spent some time with one in the dove field a few years ago, and I shot very well with it.
I had a old Winchester Model 120 Ranger a number of years ago and it shucked faster and slicker than any pump gun I've ever shot. I did not care for the location of the safety, though, so it's gone. If the SXP is anything like that 120 was, it is crazy slick indeed.
