The U.S. law enforcement pistol
The .40 caliber introduced at the 1990 S.H.O.T. Show closes the gap between
the heavy .45 charges and the internationally proven 9 x 19mm service calibers.
GLOCK was the first manufacturer to make the advantages of this balanced caliber
accessible to law enforcement agencies in a perfect pistol. Today, countless
police units in the United States and throughout the world put their trust in
the 15-round GLOCK 22.
The Gen4, just like any GLOCK pistol has the same time tested “Safe Action”
system durable exterior finish cold hammer forged barrel durability reliability
light weight ... that make GLOCK firearms famous!
The new Gen4 has several new features designed to satisfy the most
demanding consumers. It is based on a full size G17/G22 MBS (multiple back
strap) frame with a reduced short frame trigger mechanism housing. The multiple
back strap system allows the user to change the circumference of the grip to fit
their individual hand size.
The grip has three options; a short frame version, medium frame or large
frame that are easily changed and secured with a single pin.
The grip angle of the GLOCK “Safe Action” Pistol is not changed by back strap
modifications. This ensures that the shooter does not shoot high or low when
modifying the back strap or when shooting with a different GLOCK Pistol.
The smallest back strap is integrated in the GLOCK MBS Frame reducing the
trigger distance of the standard size frame by 2 mm. The medium back strap is a
2 mm back strap offering equal size of a standard frame. The large back strap is
a 4 mm back strap.
The magazine release catch of the Gen4 is reversible and enlarged. The
reversible magazine allows users to switch the catch to the left or right side
of the pistol with no additional parts.
Additionally, the Gen4 has a new Rough Textured Frame (Gen4 RTF) surface
designed to enhance grip traction and is present on the frame as well as the
interchangeable back straps.
Internally, the original recoil spring has been replaced with a dual recoil
spring assembly. The dual recoil spring assembly noticeably reduces the recoil
while simultaneously increasing the life cycle of the assembly .
