Trying to decide what will be my first CZ purchase:
Tried a stock Shadow 2 and loved everything about it - except it isn't allowed in IDPA.
The SP-01 Shadow Target II looks to be good in both USPSA Production and also IDPA in either SSP or ESP. - haven't shot one and it is the most expensive.
The CGW SP-01 is the least expensive and could be used in USPSA Production and IDPA ESP. But, it also has a 10 week wait.
Other factors: I don't shoot IDPA much - I would probably shoot a max of 5-6 times per year and I could just use my plastic defensive pistols, which is what I'm currently doing.
Of the three choices, I've only tried the Shadow 2 and it was great. Almost too good to be true compared to my Glocks and M&P pistols.
