DanP, I believe Shawn Dodson gave you a little more specific information as to how the actual technique is performed, which is what you were looking for.
A couple of people's responses here absolutely cracked me up, as they were intended to! i.e. M. Irwin, blades67, hkmp5, etc.
Dodson's preferred method is one that can be utilized as well as -
Grasp handgun in stronghand. All tech. should be utilized with a firing grip on the weapon so you have proper control over it as well as being able to contend with anything of an immediate nature. Using support hand, grasp underneath the dustcover and grip the slide (like JimmyDee explains in prior post). Keeping trigger finger (obviously) clear of the trigger guard, along the frame (in register), pull slide back slightly, just enough that you can then place trigger finger up into the chamber.
This method, as well as the one Dodson explains (I believe called the SAS tech) are best, since they can be done in complete darkness. Tactfully, and visibly, since light cannot be counted on.
Obviously, before you holster your carry pc. you chamber a round, then perform a chamber check to verify that a round was chambered. If your handgun is never out of your holster again during the course of the day, or never out of your absolute control, then you will not need to verify again.
