Umarex Walther P38
The P38 is a 9mm semi-automatic pistol that was developed by Walther arms as the service pistol of the German Wehrmacht shortly before World War II. It was intended to replace the costly Luger P08.
This P38 by Umarex (fully licensed by Walther) is a CO² powered, semi-automatic, 4.5mm BB air pistol with a blow-back action and metal top slide. True to the original it carries authentic markings and it is popular with collectors as it holds a firm place among classic military pistols.

Do you want strapped like you’re on the Eastern Front in Air Pistol Format? ... Probably a quite a niche requirement, but if so this is the air pistol for you. It has a very nice blow back action all the switches and catches are like the real thing it even has a barrel release presumably to swap it out for some mod/2nd barrel choice. Single action trigger and fixed sights. I like it.
