The SAS models come with a light melt job on the slide. Mostly just around the ejection port and at the front and rear of the slide. What's the point? Why is the SAS melt job supposed to benefit CCW'ers? It's not smaller, nor lighter except by a hair. The 239 and 229 are too heavy for no-holster pocket carry like you'd carry a bobbed revolver. Probably everybody carries these SAS Sigs in a holster 99% of the time, so what's the point of the melt job? They don't hide any better in a holster, because the holster is the same exact size whether the slide is melted or not. If anything, the melt job should round off the hammer and the end of the grip. Those are the the parts that either jabs your side or prints under your shirt and could use some trimming. So why is a melt job on a Sig better for CCW than a standard slide?
