Drive stun doesn’t use the probes (which, with proper spread and contact, cause neuromuscular incapacitation). It’s done with the cartridge off.
I used drive stun exactly one time. From there on out, if I was up close, I would discharge the taser at “point blank” range, then move the taser to a different part of the body (leg, usually) to get the spread required to achieve NMI. Worked great.
