BASIC DRAW TECHNIQUE
This drill is broken into three steps for right handers...
1) Right hand gets a firm grip on the gun, trigger finger extended, as left hand palm is simultaneously placed against belly;
2) gun is drawn and moved toward body centerline as muzzle is rotated toward target, meeting left hand a few inches in front of chest to complete two-hand grip;
3) gun in two-hand grip is extended toward target until right arm locks at eye level, and left elbow is slightly bent in a "modified Weaver grip".
I say "GRIP" and not "stance", because in a combat situation there will be NO opportunity to adopt an ideal stance, so you shouldn't practice and come to depend on one. The goal is to be able to shoot well no matter how you are standing.
A technique from Israel that is excellent for semi-autos.
It begins the same, but as the piece is thrust forward with the "strong hand," the weak hand, held close to the body grasps the slide, cocking the piece in the same motion as the strong hand extends....saves precious fractions of a second to bring yourself "into battery."
