All Glock pistols have no manual safeties, instead using Glock’s unique ‘safe action,’ consisting of three separate automatic safety mechanisms. This gives the pistol the safe carrying of a double action only weapon, without the heavy trigger pull. The pistol has a steel slide and polymer frame, which reduces weight while increasing reliability and toughness.
The Glock 17 features a polygonally rifled barrel, a 17 round magazine and fully adjustable sights. The pistol weighs 625 grams unloaded.
