Here is a video from our recent Foundations Handgun Course where I break down administrative unholster and re-holstering of the gun.
Grip the gun with consistency (the same way every time). We also want to front load; we do as much as we can as early as we can in the process.
Clear - Snatch the gun straight up out of the holster until the shoulder binds. This will ensure a consistent and reliable draw from the holster for all guns and all holsters. Additionally, ride the rails of your body for a consistent reference for the same draw every time.
Lock - As the gun is snatched from the holster you hit a stop point, and the muzzle rotates up on its own. Don’t drop your elbow (slow and extra movement).
Join/Ready - From the lock position bring the gun forward for a full two handed grip on the gun compressed against your chest and under the shooting eye.
Re-holster - Again, consistency…maintain a full firing grip all the way to the holster with the gun secure. Don’t get lazy. Your body and your mind learn gun handling on the way out and on the way back. If you get lazy on the way back, your skills will breakdown when you need them the most.
