The Custom Works P320 AXG Classic features the newly developed AXG metal grip module, precision machined with deep undercuts, and an extended beavertail for an ergonomic, comfortable fit, and is fitted with custom Hogue Walnut Grip panels for complete control. The P320 AXG Classic utilizes the short-reach trigger, and includes a SIG Pro Series removable optics plate with dovetail XRAY3 day/night rear sights and XRAY3 day/night front sight and also comes with (3) P320 magazines. in short this has an aluminum grip module and wood grips. Hope this helps.

I found my information on several websites using the UPC code and model number, they all say the same. It has a aluminum grip module/frame with walnut wood grip panels. Even on the link paul provided, they say axg aluminum module grip but they're talking about the frame like on prepped guns, with walnut wood grip inserts. So I still stand behind them being wood with an aluminum grip module/frame. Hope this helps.

Randy typically gives good answers, but he's incorrect on this one, James and Josh are giving answers based off the link randy provided and not doing their own research.
Randy linked to the info on Sigs website for model
"320AXGCA-9-CW-CL-R2"
The model you are i inquiring about is model "
320AXGCA-9-CW-C"
They ate not the same, the one you linked to has aluminum grips.
As listed by EVERY online retailer selling it.
