The base CZ TS 2 model, as featured in the JustinOpinion video above seems like a strange, slightly budget TS, with the non-adjustable rear sights, non-paddle mag release, and lack of a thumb rest.
The Racing Green / Deep Bronze model looks like it has all the same features as the TSO, along with a similar price.
Other than the price difference, would there be any reason to get the base model over the green / bronze ? Does the base model fit in an IPSC division that the others don't ?
