The Tactical Sport is no where near the same as a Witness Tactical II.
The TS is a full dust cover, cone barrel, single action competition gun that includes a magwell in the frame, and has an MSRP around $1,000
The Witness Tactical II is a single/double action gun with a shortened barrel (compact) and ported for duty/carry purposes, and goes for around $450 ballpark
That should help clear up any differences.
