PLEASE NOTE: Always empty a firearm before cleaning. Be certain to remove the magazine and any ammunition in the firearm’s chamber before cleaning. Be sure no ammunition is present in the surrounding area while cleaning.

Handgun Maintenance: Cleaning Instructions
Before cleaning your must first disassemble your STI handgun. For instruction please reference the STI Owners manual that came with your pistol or reference the PDF version at the link below
- Clean slide using a nylon brush and cleaning solvent; scrub away any powder residue, particularly on the slide rails. Wipe slide clean with a lint-free cotton cloth. Inspect the slide for damage or signs of unusual wear.
- Clean frame with a nylon brush and cleaning solvent; scrub away any powder residue, particularly on the frame rails. Wipe frame clean with a lint-free cotton cloth. Inspect the frame for damage or signs of unusual wear.
- Saturate a cotton pad with cleaning solvent and attach it to the bore cleaning rod; make several passes through the bore with the pad to saturate and loosen metallic and powder residues. Allow the barrel to soak for a few moments, then attach the bore brush to the bore cleaning rod, saturate the bristles with cleaning sol-vent, and make several passes through the bore with the bore brush. Inspect the bore for residues and repeat cleaning with the bore brush as necessary. Note: Always keep the bore brush saturated with cleaning solvent to prevent damage to the bore and/or compensator, and make each pass through the barrel a complete pass starting at the breach end of the barrel and continuing until the entire bristle section of the bore brush is outside the barrel or compensator – do not change directions when the brush is inside the barrel or compensator. Once the bore is free of residues, attach a clean cotton pad to the bore cleaning rod, saturate it with cleaning solvent and make several passes though the bore. Continue changing pads until the pad emerges clean. Finally, dry the bore with a clean cotton pad, apply a very small amount of high-quality lubricant to a clean cotton pad and make several passes through the barrel to lubricate it.
- Clean all springs, pins and other components with cleaning solvent and wipe them dry with a lint-free cotton cloth. Inspect each part for damage or signs of unusual wear.
- Apply a coating of high-quality lubricating oil to all moving parts, paying special attention to the slide and frame rails, and reassemble the handgun. To reduce the possibility of corrosion, apply a very light coating of lubricating oil to all external steel parts.
Note: If any handgun components show signs of damage or unusual or excessive wear, stop using the firearm immediately and contact STI International for assistance.
