PX4 Medium Backstraps by LOK Grips

The LOK PX4 backstrap is an easy way to add texture to your PX4 full size. The checkering gradually changes across the width of the backstrap so that the texture is both aggressive enough to provide you incredible grip, without the sides of the backstrap tearing up your skin, clothing, or surroundings. The LOK backstrap is also much easier to install and remove than the factory polymer backstraps,add and eliminates the need for the steel retaining fork. The shape of the backstraps is similar to the factory “medium” size.

The backstrap is available in two materials:

  • Anodized Aluminum: Lightweight and durable. Recommended for concealed carry or duty applications.
  • Brass: Adds weight (approximately 2.5 oz) to the rear of the gun to improve balance and minimize recoil. Recommended for shooters who want to add every ounce of performance to their PX4.

Installation:

  • Ensure that your firearm is unloaded.
  • Remove the retaining wire fork by inserting a flathead screwdriver under the exposed portion of the fork and twisting. Then use the screwdriver to pry the retaining fork out, being careful not to mar your frame.
  • Remove your backstrap by inserting the flathead screwdriver between the frame and backstrap at the bottom of the magwell and twisting.
  • With the slide forward and the hammer down, push onto the hammer spring plug with the corner of a bench or other sturdy object. With the spring plug depressed, use a ⅛” punch to press the hammer spring plug retaining pin out.
  • Slide the LOK backstrap onto the pistol.
  • Push the hammer spring plug back into position and seat the provided coil pin with a ⅛” roll pin punch.
