Commander Field-Strip
Howdy Amadeus,
Assuming that you're right-handed:
Stand the pistol muzzle up and grip the slide like a hammer in your right hand. Extend your thumb over the spring plug and push it in with the tip of your thumb.. Get a good purchase on the thing...It's under spring pressure and will fly out. Hold it in while you rotate the bushing clockwise.
When it stops, slowly release the plug until the spring is free. Remove the plug, and lay it aside. Push the slide back until the stop aligns with the takedown notch...the small, half moon-shaped notch. Push the slidestop
out from the right side until it clears the slide, and pull it the rest of the way out.
Caveat: Do NOT let the muzzle point directly at your face when you rotate the bushing clockwise. If the plug gets loose from your thumb, you can get "shot"by the plug. Angle it away from your face.
Pull the slide forward off the frame. Pull the guide rod and spring out from the rear. Rotate the bushing counter-clockwise until it stops and pull it out.
remove the barrel. Done!
20 seconds is a bit long. My time for a complete detail-strip, frame and slide...starting with an assembled pistol, is 52 seconds...but I've done it a
few thousand times over the last 40 years.
Luck!
