SJoe,

Yes, you can execute a fast, short-stroke muzzle strike with an attached 1/2/3 point sling. In fact, the limitation of a short stroke is probably better in the long run, as without something stopping you, you may be tempted to 'reach out' too far, putting yourself off balance and presenting an opportunity for the BG to grab your barrel. The downside is you need to be very close to the BG to execute the strike, which means you let him in too close to begin with. Since this appears to have a heavy LE flavor (and comes with the associated ROE), TR appears to have a very good solution.

As for the rifle management after transition question, yes it will swing around, but if you're using a one-handed device (ASP, OC, etc), you can stabilize the rifle with your weak hand, as the rifle is hanging near that side anyhow. If you plan to go hands-on with the BG on the ground with a slung rifle, things are going to get interesting regardless.

Assuming in the scenario you're LE, I can only guess at proper department ROE but I'd bet that the transition to Taser/OC would have occured very early in the situation while the BG was still a good distance from you, and that your Plan B was to use the rifle for striking or shooting.

JPH, you're referring to the Tueller drill. As you said, with practice, someone can sucessfully draw and engage a closing BG before the BG gets within contact distance, so the lesson here is...you got it, practice your draw to fire drills so you're capable of doing it. BTW, 15m (almost 50 feet) is a long way away and encompasses a whole lot of people in a mall or busy sidewalk.
