GLOCK Gen4 pistols have a few key innovations that make the gun suitable for smaller profile hands and varying experience levels: interchangeable backstraps, a reversible magazine catch, a dual recoil spring assemble, and a rough textured frame. 
  
Modular Back Strap System  
GLOCK Gen4 pistols come with a modular back strap system, allowing you to choose the back strap that best fits your grip without changing your grip angle. Two back straps are included with your Gen4 pistol: medium, which adds 8/100 of an inch from the back of the grip to the trigger, and large, which adds 16/100 of an inch. The smallest back strap is incorporated into the frame of the pistol. 
  
Enlarged Reversible Magazine Catch 
The magazine release catch of the Gen4 is reversible and enlarged, allowing you to easily switch the catch to the left or right side of the pistol with no additional parts. 
  
Dual Recoil Spring Assembly 
The Gen4 pistols have been upgraded to a dual recoil spring assembly. The dual recoil spring assembly noticeably reduces the recoil you feel, while simultaneously increasing its lifespan. 
  
Rough Textured Frame 
The Gen4 has a new Rough Textured Frame (RTF) surface designed to enhance grip traction, present on the frame as well as the interchangeable back straps.
