My new replacement P-08 blowback arrived yesterday. I gave it a go this morning. The difference between my original pistol and this replacement is like night and day!! I ran two(2) CO2 cylinders throught it......This one works 100% with no malfunctions....it was lubricated well at the factory(mine was dry as a bone). the mag fits nicely in the mag well, etc. I am very pleased with this P-08 and Umarex Customer Service.
