Optic-ready slide (no optic included), 4.7-inch 9mm barrel, flat/X-Series trigger feel, and three 17-round steel magazines. Sig part number W320F-9-BXR3-TXG-PRO, UPC 798681628896. This listing is for the P320 Pro Fullsize with TXG grip, optic ready (no optic) only.
TXG: Tungsten Weight in a Polymer Grip
Sig defines TXG as tungsten-infused polymer — the flex of polymer with added mass for softer recoil and less muzzle flip on follow-ups. That is why competition and precision shooters reach for a heavier grip module on a duty-size P320.

- XRAY3 day/night sights installed.
- 4.7" barrel, Nitron finish, M1913 rail.

Excellent handgun that is well balanced with minimal felt recoil. The weighted grip is amazing in contributing to the overall function of the gun. I have ordered the tungsten insert for my X Carry due to its obvious benefit.
