Firearms Maintenance

Instructor Sele: A dirty firearm is an unreliable firearm. An unreliable firearm in a security context is a liability — to you, to your team, and to your client. Maintenance is not optional and it is not only the armourer's job. Know your weapon. Keep it clean.

Section 1 — Why Maintenance Matters

Carbon fouling, moisture, and debris accumulate in a firearm with every round fired — and even from carrying. A poorly maintained weapon is more likely to: fail to fire when needed most; experience stovepipes and failure to feed; develop corrosion that permanently damages components; fire unintentionally due to debris interfering with safety mechanisms.

Section 2 — The Cleaning Kit

Every assigned guard must be familiar with the standard cleaning kit: cleaning rod — pushes patches through the barrel; bore brush — loosens carbon fouling inside the barrel; patches — cotton squares used to clean and dry the barrel; cleaning solvent — dissolves carbon and powder residue; lubricating oil — protects metal surfaces and ensures smooth operation; toothbrush (stiff) — cleans the frame, slide rails, and action; dry cloth — wipes down external surfaces.

Section 3 — Basic Cleaning Procedure (After Firing)

Clear the weapon — confirm it is unloaded and safe before beginning. Field strip — disassemble into major components (frame, slide, barrel, recoil spring). Clean the barrel — run solvent-soaked patches through until clean; follow with dry patches; finish with a lightly oiled patch.

Clean the slide — use the brush to remove carbon from the rails, breech face, and ejector. Clean the frame — clean the rails, magazine well, and trigger group. Lubricate — apply a light film of oil to all metal-on-metal contact surfaces (rails, barrel hood, feed ramp). Reassemble — reverse the field strip; conduct a function check. Log — record the cleaning in the maintenance log.

Section 4 — Routine Inspection (No Firing)

Even if no rounds have been fired, a monthly inspection is required: check for corrosion, particularly in high-humidity environments; inspect the magazine for damage, feed lip deformation, or weak spring tension; function check — ensure the trigger, safety, slide, and magazine release operate correctly; wipe down the exterior with a lightly oiled cloth.

Key Points
  • A clean firearm is a reliable firearm — maintenance is an operational responsibility
  • Always confirm the weapon is unloaded before beginning any cleaning
  • Field strip → clean → lubricate → reassemble → function check — in that order, every time
  • A monthly inspection is required even when no rounds have been fired
  • Record every cleaning and inspection in the maintenance log
Field Note · Instructor Sele

"I conducted a surprise inspection and found a guard's pistol with a barrel so fouled with carbon that I could barely run a cleaning rod through it. He told me 'the armourer is supposed to clean it.' The armourer maintains the inventory. You maintain your weapon. If your car has a flat tyre, you don't wait for a mechanic to fix what you could fix yourself. Know your weapon. Own your weapon. Keep it clean."
