This is a brand new OEM Sig Sauer P320 X-Series Carry Medium grip shell for pistols chambered in 9mm, .40 S&W, and .357 SIG only. This will not work on P320's chambered in .45 ACP. This grip shell is white and ready to be dyed or finished in the color of your choice!

Note that this grip shell does not have the grip weight or magazine well / funnel like the full size X-5 grip. Additionally it appears that only the newer style 17rd and 21rd mags fit this grip shell.
