The model 338 is a BB caliber semi automatic CO2 pistol with 18 round BB magazine. The 338 is a replica of the Walther P38 military pistol. I just finished resealing this pistol and this will be the third time I've shot it. It is averaging 363fps. I will be shooting at 25 feet off hand. 1986-1991 360 fps. BB Caliber .177 CO2 Semi-Auto 18 Shot Magazine,
I have a Z-77, which is just a 338 in a clam shell folding stock, made to look like an Uzi. Nice BB gun. I also found a 338 barrel sleeve, so I can take the 338 out of the stock and shoot it as a pistol. The Z-77 soda straw barrel is a little longer than the 338 barrel sleeve, so it looks a little goofy as a pistol, but it works just fine.
Would like to have the Z-77
