Mike Hughes, the rangemaster at the Gunsite Training Academy in Paulden, Arizona, explains how to enter a house while holding a pistol. The first step is to scan the door and assess where the hinges and the doorknob are (as a sidenote Hughes first references “hinges in the video, but he means door knob”). During this step, the gun is held close to the chest but aimed forward.

The next step is to push the door open with one hand and take a few steps back. This allows the shooter time to grip the pistol with both hands and assess the interior of the structure. Once the shooters has assessed the interior, he enters the building and puts his back against the wall. If there are other closed doors in the interior, the aforementioned steps are done again. Each assessment of an interior is done by dividing the room visually, which Hughes calls “pie-ing.”
