Magazine Pouch

Commonly shortened to mag pouch, this is a device to hold extra magazines which fastens to the shooter's belt.

Straddle Floorplate

Deterrent

Handspanner

German for Hand-Cocking or Cocker/De-Cocker. A type of action on a break-open gun or rifle where, in place of a traditional top tang safety, a somewhat more robust tab is fitted. Normally such a gun is carried in the field loaded, but with the action not cocked, an exceedingly safe condition. Then, when ready to fire, the shooter, instead of pushing a safety tab forward, pushes this larger tab forward, cocking the mainspring, making the gun ready to fire. Then, if the shot is not taken, he may simply slide this tab rearwards again, de-cocking the gun and returning it to the still-loaded, but very safe position.

Martini

He is regarded as one of the most successful firearms designers of the 20th century, in the development of modern automatic and semi-automatic firearms, and is credited with 128 gun patents. He made his first firearm at age 13 in his father's gun shop, and was awarded his first patent on October 7, 1879 at the age of 24.
