The Walther P-38 from Umarex is designed to give shooters a realistic looking and operating P-38 air pistol. On every level Umarex has met and exceeded this goal. The operational system is blow-back which mimics the way a real P-38 fires. This P-38 disassembles the same way the original P-38 does so much that it could be used to train someone how to disassemble an original. With an all metal construction the P-38 air gun also weighs as much as the original WWII P-38 does further adding to the realistic look and feel of the air pistol.
