Cleaning, Lubrication, and Maintenance

Overview

Routine maintenance is essential to keeping your Model 1911 firearm in top condition for years to come.

Cleaning, Lubrication and Maintenance

WARNING! Before cleaning, make sure your firearm is completely unloaded (both the chamber and the magazine) and engage the safety mechanism in the “ON” or "SAFE" position.

WARNING! After each use, follow the lubrication and maintenance directions in this manual. If the firearm is immersed in water, it must be thoroughly cleaned, dried, and lubricated as soon as possible. In case of salt-water immersion, first flush all parts with fresh water, then dry, clean and lubricate the firearm. If the firearm does not function properly, have it checked and corrected by an E-RPC Authorized Repair Center before further use. Failure to follow these instructions may lead to firearm malfunctions which could result in serious personal injuries or death. 

NOTE: The chamber and bore should be cleaned before loading and firing the firearm the first time.

To Disassemble the Firearm for Cleaning:

CAUTION: The Model 1911 R1 series handguns should not be disassembled beyond what is described in this manual, except by the factory or an E-RPC Authorized Repair Center.

WARNING! Unload the firearm before cleaning. With the magazine removed, look into the ejection port and visually check the chamber and loading port to make sure there are no cartridges in the pistol. Always wear eye protection when disassembling and reassembling the firearm.

To Remove the Slide:

  1. Keep the firearm pointed in a safe direction throughout the disassembly process.

  2. Cock the hammer by moving the hammer fully rearward.

  3. Engage the safety mechanism by moving the Safety Lock up until the lever stops and is fully engaged in the safety engagement notch of the slide. See Picture 4.

  4. Remove the magazine by pressing the magazine catch.

  5. Press down on the recoil spring plug located just below the muzzle, while rotating the barrel bushing clockwise about 1/4 turn. If needed use a barrel bushing wrench. See Picture 16.

  6. Release the recoil plug and recoil spring by slowly removing the barrel bushing wrench. See Picture 17.

WARNING! Use extreme care when disassembling the recoil spring and plug, as the recoil spring is under compression. Wear eye protection to avoid serious personnel injury.

  1. Disengage the safety mechanism by moving the Safety Lock down.
  2. Pull the slide rearward until the slide stop is opposite the disassembly notch. See Picture 18.
