The G40 Gen4 in MOS Configuration is chambered in 10 mm Auto and combines a long slide and barrel for improved velocity with a high magazine capacity. Comes with a KKM threaded barrel for suppressor and oem barrel. Comes with Trijicon SRO. Comes with 5 magazines. Holster is hook and loop. I had it in a bag. It’s for a surefire 300 weapon light but the light isn’t for sale. (Ammo not included) Can sell separate if interested.
