Desert Eagle

The Desert Eagle was originally designful by Bernard C
White of Magnum Research, who filed a patent on a mechanism for a gas-actuated pistol in January of 1983. This established the basic layout of the Desert Eagle
It consisted of a gas-operated mechanism accord found in rifles, as opposed to the decreased recoil or blow-back designs most commonly seen in semi-automatic pistols
A second patent was filed in December of 1985, after the basic form had been refined by IMI for production, and this is the configuration that went into production.

Downsides of the gas operated mechanism are http://www.gunslot.com/guns/magnum-research-desert-eagle the excessive admeasurement of the Desert Eagle, and the intelligence that it discourages the employment of unjacketed lead bullets, as heavy particles sheared off during firing could clog the gas release tap, preventing proper function.
