Mike, it is my understanding that Indiana statutes require that any person who carries a stun gun must also have a handgun permit.
Applicability of handgun provisions
Sec. 4. [b]IC 35-47-2 applies to an electronic stun weapon or taser.
Carrying a handgun without a license or by person convicted of domestic battery
Sec. 1. (a) Except as provided in subsection (b) and section 2 of this chapter, a person shall not carry a handgun in any vehicle or on or about the person's body, except in the person's dwelling, on the person's property or fixed place of business, without a license issued under this chapter being in the person's possession.
(b) Unless the person's right to possess a firearm has been restored under IC 35-47-4-7, a person who has been convicted of domestic battery under IC 35-42-2-1.3 may not possess or carry a handgun in any vehicle or on or about the person's body in the person's dwelling or on the person's property or fixed place of business.
As added by P.L.311-1983, SEC.32. Amended by P.L.326-1987, SEC.1; P.L.195-2003, SEC.6; P.L.98-2004, SEC.155; P.L.118-2007, SEC.35.
I interpret this to require any person carrying a stun gun out in public must also possess a valid handgun permit, and think it's important that forum readers understand their legal obligations before purchasing or carrying a stun-gun
