Some gathered thoughts on teaching the drawstrokes:
For those with strength, economy of motion, or other mechanical deficiencies; I prefer to teach the elements of 2/3/4 with a 5lb weightplate. The student receives more feedback if they are driving the weapon so quickly as to be unable to bring it to a controlled stop at any point in the overall movement (to whit: overdriving).
E.g. Starting position: the student casually indexes the plate over their carry position and approximate carry height, in a fascimile of a firing grip with the hand of choice; with the non-carrying hand hanging loosely at their side. Most thread the social and ring fingers through the hole in the plate, have the index finger in high register up near to the plate's rim, and the pinky flares out flat against the side of the plate itself. (Optional focal element: student visually indexes onto something at the far end of the room and will remain so focused until dictated later.)
...they then INHALE and ROW the plate up to full-compression or an appropriate tactile reference point, whichever arrives first given their physical capabilities. The non-carrying hand moves to press flat against high\center-of-chest, as this happens.
- AIWB users rowing up until the length of their flagged thumb, base of their thumb and the edge of their wrist indexing below the pectoral muscle and with their shooting-side elbow flared outwards and to the side.
- HIWB users rowing up until the flagged thumb indexes against the outboard edge of their pectoral muscle, elbow flared backwards and upwards.
...they then lock their wrist at its present and neutral angle, maintain the present acute angle of the elbow, and fold the carrying-side elbow down to touch their floating-ribs\flanks while keeping the plate oriented directly forwards.
- AIWB: the shooting-side elbow folds down to touch the ribs, and the weapon reorients from horizontal to vertical incidental to this.
- HIWB: the shooting-side elbow advances forward to touch the ribs, and the weapon reorients from the downward angle of the TPI to vertical\facing-downrange.
...(if working a two-handed press-out, the non-carrying hand collects onto the weight-plate at this time) they then EXHALE and PRESS the plate outwards and upwards, until the plate rises into and intrudes upon their visual plane.
(Optional focal element: student shifts focus from the distant point to the top edge of the plate, building a pseudo sight-picture.)
((Students pressing out a plate with the hand opposite of their dominant eye will turn their chin as they begin the exhale, sufficient and in order to position their dominant eye behind the plate without deviating their shoulders or unevenly bending their elbows.))
(((If working one-hand only press-outs, then the non-carrying hand remains flat to the chest and the presently shooting-side shoulder drives more aggressively behind the plate during the press-out itself.)))
...they should arrive at an end-state of having empty lungs, full extension, and optionally a pseudo sight-picture with appropriate turning of the head.
...Inhale and retract back, reorient the elbow, and exhale while returning the plate downwards back to the starting position.
- AIWB: reorient the elbow upwards and outboard, with a locked and neutral wrist, maintained acute elbow angle
- HIWB: draw the elbow further rearwards and then upwards, with a locked and neutral wrist, maintained acute elbow angle
...repeat to prescription.
As relates to garment clearance, I teach two methods: a two-handed and a single-handed method.
With two hands:
...both hands sweep upwards from below the belt-line, with all fingers clawing\brushing at the garment's hemline upwards before the thumbs join to pinch at the fabric gathering within each grasp: this so as not to over-emphasize the claw\sweep that may have fingertips snagging upon the gunbelt, and to capture bunched fabric if the hemline is not captured at the beginning of the movement.
...both clasping hands attempt to rise until the bases of each thumb reach and stop beneath each pectoral muscle or the elasticity\give of the fabric arrests movement whichever arrives first so long as the weapon's grip is wholly exposed; this so as to function with fully-zipped up inelastic hardshell jackets, fully buttoned-up shirts, t-shirts\polos, and hoodies.
...the support hand maintains wrist-pressure against the collected garment as it extends flat to the high\center-chest, while the shooting-side maintains active wrist-pressure as the wrist tracks over the gathered garment until the shooting-hand arrives upon the holstered weapon's tang - flagged thumb (so as to avoid pinching an undergarment and to allow the hand to fully descend onto the weapon), hand rolled sufficiently far forward\downwards onto the weapon as to appropriately index for a firing grip when the weapon is drawn from the holster, and trigger finger straight and oriented such as to arrive at a positive register upon-the-slide\into-the-ejection-port when the weapon is drawn from the holster (count 1).
With one hand:
...the shooting hand sweeps upward from below the belt-line, with the four fingers clawing\brushing at the garment's center-hemline upwards before the thumb pinches towards the fingertips; this so that the garment's hemline or fabric is clasped between the length of the thumb and the fingertips.
...the clasping hand and captive fabric then rising upwards and moving to the outboard-side such that the base of the thumb presses against the outboard edge of the pectoral muscle; this such that the fabric has maximum tension and a minimum of hanging or slack fabric remaining. Enabling this, the shooting-side elbow should track rearwards and upwards.
...the shooting-side wrist presses against the fabric immediately behind the clasp, pinning the fabric against the ribs adjacent to the pectoral muscle; until the forearm then advancing forward assumes and maintains the capturing pressure against the ribs to hold that fabric, as the hand then descends to arrive upon the holstered weapon's tag with a flagged thumb, hand rolled sufficiently far forward\downwards onto the weapon weapon as to appropriately index for a firing grip when the weapon is drawn from the holster, and trigger finger straight and oriented such as to arrive at a positive register upon-the-slide\into-the-ejection-port when the weapon is drawn from the holster (count 1).
