Keep your P365 operating flawlessly and extend its lifespan with this complete cleaning and maintenance guide — based on SIG’s own recommendations and enhanced with practical tips from real users.
What you’ll need to clean your sig sauer p365
- CLP (Cleaner, Lubricant, Protectant)
- Bore brush (9mm)
- Cleaning rod with patch holder or bore snake
- Nylon brush or soft-bristled toothbrush
- Q-tips or cleaning swabs
- Lint-free cloth or microfiber towel
Pro tip: Avoid spraying CLP directly into the striker channel — this can lead to light primer strikes over time.
Field-strip your p365 safely
- Drop the magazine and clear the chamber.
- Lock the slide back and visually inspect.
- Push the takedown lever down (approx. 6:30 position).
- Release the slide and remove the barrel and recoil spring.
- Your P365 is now field-stripped and ready to clean.
Deep cleaning process
clean the slide
Spray with CLP while holding the slide downward. Scrub rails and extractor using a nylon brush. Use Q-tips for tight spaces, especially around the breech face.
clean the barrel
Push a CLP-soaked bore brush from chamber to muzzle. Repeat with clean patches until they come out nearly spotless. Finish with a bore snake if desired — it leaves the rifling gleaming.
clean the frame
Lightly scrub metal-on-metal contact areas (rails, locking block). Wipe down all surfaces with a clean cloth.
Lubrication tips
Apply light lube to:
- Slide rails (both frame and slide)
- Barrel hood and locking lugs
- Recoil spring ends
Keep the inside of the barrel dry — no oil or grease.
Reassemble and perform a function check
- Reinsert the barrel and recoil spring.
- Align slide to frame and pull back fully.
- Return takedown lever to the locked position.
- Perform a function test:
- Rack slide
- Pull trigger (dry fire)
- Reset trigger by cycling slide while holding trigger
Done right, your SIG should now feel smooth, crisp and reliable.
FAQs
How often should i clean my sig p365?
After every 200–300 rounds is a safe routine. If you carry daily or live in dusty/humid conditions, consider wiping down key components weekly and deep cleaning monthly.
Is it okay to dry fire a sig p365?
Yes — SIG Sauer confirms that the P365 can be dry fired safely without damage. That said, using a snap cap is recommended for extended dry fire sessions to preserve striker longevity.
