It does look like a Walther, but I'm no expert.
Take a look at his fingers in the screenshot. If you are going to aim a firearm, you need to be prepared to pull the trigger. He isn't.
Had a blast (literally) today. "Wasted" lots of ammo-P85, P89, PT911, 22/45, H&K USP .40c. Like that H&K-too bad it belongs to my son!
So many firearms, so little money.
