I have this model of DE. 7 in the mag for a gun larger than some baseball bats? The velocity was slightly higher than the S&W .500 and it WAS by a VERY credible source testing them both with a Chronograph and I saw everything on video first hand with NO edits. Last but not least, if you havent personally shot a Desert Eagle, throw out everything youve heard about the gun. Theres no justification for it, except for having a raucous good time and burning through all those cash wedding gifts when your spouse isnt looking. I shoot one-handed with the DE .50, and Im no agent. Use max loads of slow powders like Acc #9 or H-110 and magnum primers. The gun measures 10.75" in length with a 6" barrel, or 14.75" in a 10" barrel available in black as an aftermarket item. Save big on a new desert eagle pistol. A good reason I bought a desert eagle and probably the only good reason On a scale of zero to five, with five being an Airlight and zero being a flaming porcupine, the Desert Eagle is a one.
