What do you mean by unamended? There is no such thing any more.
There was SB93, which was pretty darn close to Constitutional Carry, then it had SSA1 replace it, which was Constitutional Carry with an optional permit, which had SSA2 replace it which is a 'shall issue' permit with training law and then was amended by SSA2-SA1 and SSA2-SA4, which tweaked some legalese and the training requirement. If you read the current SB93, it is the output of all that.
There are individual threads that explain the individual parts.
