Bring in a few portable chairs and work on seated draw in seated position shooting.
The seated position gun handling is highly relevant because we do end up seated very often not to mention in a vehicle which is beyond the scope of the class but at least gives some exposure to the notion of drawing from seated.
Set up the drill and basically demo how to manipulate the body as needed, depending on where they now prefer to carry 4:00 or appendix and get to the pistol, draw and then shoot from seated. At the first phase, have them shoot just 4:00 or just slightly off to the left from seated with a freestyle grip and then take the progression of getting out of the chair.
The next progression is to have them get out of the chair from a seated position where now they draw and simultaneously gather their feet to take first steps, get away from the chair and shoot from a secondary position there from. There are a plurality of reasons why they may want to shoot from seated or from standing position, and of course one class can't cover all the possible contexts of either situation. It's not the point of this class to thoroughly describe when to shoot from seated and when to shoot from standing position. This is highly contextual and we are simply working on the mechanics to get out of that chair, get the gun out, and engage a target as quickly and accurately as possible.
Further, mechanics tend to erode in these compromise shooting positions, so this is a self-exploration for the student to understand that their ability to maintain sight alignment, sight picture, and trigger mechanics may have some erosion compared with their range freestyle standard stance. It's important they understand this and of course work on it in these compromise positions to build their skill sets.
Note in the more advanced courses in student shooting there's discussion on diamonds, seated shooting and one handed seated shooting is taught and put forth by A-Wrestling of Don Gulla. You can check out those additional modules.
