Regular PDN viewers know that Rob Pincus is a big fan of the high compressed ready position, not any type of extended ready position. There are numerous reasons for this preference, but the main ones are efficiency and consistency.
You can do more things with the pistol in a compressed ready as opposed to an extended ready. He demonstrates these with a Laser Ammo Pro Laser Training Pistol, a worthy addition to your self-defense gear. Going around corners and cover with the gun in an extended ready exposes it — not a good idea. In an active shooter situation, having the gun in an extended ready looks more threatening than if it is in a compressed ready position, and that can get you shot.
Rob advocates getting used to driving the gun out from the high compressed ready position. This motion is consistent with drawing the gun from the holster and driving it out to take a shot.
Another problem with an extended ready position is that shooters often put their finger on the trigger when holding the gun in that position. The Laser Ammo Pro Laser Training Pistol has a useful feature called the Tattletale: a patented sensor design detects even the slightest intrusion into the trigger guard and sets off an alarm, warning the shooter about a potential discharge for shooting drills and handgun training. The device distinguishes between deliberate actions and unintentional incursions into the trigger guard. When an unintentional intrusion is detected, an alarm sounds.
The Laser Ammo Pro Laser Training Pistol features the ability to change weighted magazines, and the laser can be integrated with a variety of training targets and simulators. The lasers can be infrared or traditional red, and you can adjust windage and elevation to make sure your shots go where you intend them to.
