The company Glock, which has been producing high-quality firearms since 1963, is now world-renowned for it. Especially the handguns are considered to be extremely precise and easy to handle. The Glock 20 in 10mm Auto offers the shooter massive firepower and high accuracy. The proven, recoil-dampening Glock polymer grip significantly reduces felt recoil, even with strong calibers. With a muzzle energy of 750 Joules and a magazine capacity of 15 rounds, the Glock 20 is the optimal companion for any hunt and a reliable partner for the finishing shot, even with formidable game. The Gen4 models take over the already proven features of the Gen3 previous models and optimize them with additional innovative features. The proven Safe Action system, a textured polymer grip with finger grooves and a tactical mounting rail in front of the trigger guard, as well as the precise barrel with polygonal barrel profile of the Gen3 have been expanded with several innovations. The new GEN4 features include a grip (also with finger grooves) with a roughened RTF surface for improved grip and the MBS Multiple Back Strap system with adjustable backstraps. The MBS Multiple Back Strap grip offers a significant advantage: the circumference of the grip can be adjusted to the individual hand size and needs of the shooter using the included backstraps (4 pieces, with and without beavertail). The magazine holder has a larger contact surface and is interchangeable, which increases user-friendliness and allows for adjustment for left or right-handed users. In addition, all GLOCK Gen4 models are equipped with a tandem closing spring. This reduces recoil and has also proven to have a very high durability. The sights have also been improved; the front sight is no longer clamped but screwed in, which makes changing it significantly easier.
