Now for the big "secret" to cleaning a semi-auto: An air compressor.

Use the air compressor to blow out all the solvent from the slide.

Then spray the lower and scrub it with the toothbrush.

Spray on some more solvent and then use the air to blow it dry.

Everything can be wiped down and is ready for lubrication before reassembly.

We start with oiling the barrel locking lugs with a small amount of lubricating oil.

I also oil the exterior of the barrel, so that it will slide easily through the barrel bushing.

Also a drop on the hinge pin.
