Speaking only for myself, I’m not sure drawing a weapon and putting it between your legs while riding a motorcycle is a good idea.
A bump or dip the the road, a quick maneuver, hard braking all may cause the weapon to fall onto the road. Now it’s behind you and useless. At the academy we were taught that the weapon stays in the holster till you are out of the car/off the bike. At motor school they said you can remove the glove from your strong side hand in anticipation of drawing. But the weapon stays in your holster until you dismount. It’s human nature to want to grab a weapon that’s shifting around, and you need your hands free to operate the controls.
If you carry a gun while riding, you may want to learn to draw and shoot and reload while wearing gloves. Practice stopping the bike, setting it on the side stand or just dumping it, drawing the weapon and shooting it while wearing gloves.
From 15mph:
1 come to a complete stop.
2 hit engine stop button.
3 either set the bike on the side stand or dump it on its side.
4 practice dismounting from both sides.
5 get behind the bike and take up either a kneeling or prone position.
6 draw weapon and engage threat.
A little tactical preparation and practice will more than make up for the time you think you are saving by drawing the weapon and placing it between you legs while the bike is still moving.
This is what I was taught, this is what I pass on. Feel free to consider it, or ignore it.
