I have a lightly used Sig P320 AXG combat for sale or trade. It has only had about 300 rounds of various 115gr, 124gr, and 147gr ammo through it and has had zero malfunctions. I had a RMR on it and it includes the C&H Precision plate with screws for Trijicon RMR / SRO / RCR / Holosun 407C / 507C / 507Comp / C&H EDC-XL / COMP. It will fit the DPP right out of the box without the adapter so you'll have lots of flexibility. Comes with the whole kit as new with the three 21rd magazines and the nice custom works case.
Only trade would be for a Beretta 92XI SAO Sabbia or Squalo.
