My opinion, buy a stock CZ 75B or SP-01 and add parts as your requirements and budget allows. I am partial to my stainless 75B due to corrosion resistance and resistance to wear from repeated draws.
Don't make the mistake of buying a pistol which is not on the IDPA list in anticipation of it becoming legal in the future. I bought a Shadow T from CZC for SSP. It was perfectly legal for SSP when I purchased it. IDPA changed the requirements and it is no longer legal in SSP. It is still legal in CDP however.
In local matches I wouldn't be too concerned. I would shoot what I wanted to.
Unfortunately, there are problems with this approach.
- I'd rather get a pre-B version of the CZ 75 for the better trigger.
- Adding parts to a gun is generally not allowed in the SSP division, especially if the part is visible.
- Adding parts to a gun to make it more competitive is invariably more expensive than buying a competition model that already includes those parts. This is especially true even with some allowable parts such as an adjustable rear sight.
- I'm not interested in building another ESP gun where those changes might be legal. I've already got several excellent ESP guns. I'm looking for a steel gun to replace my polymer M&P 9 Pro.
If only IDPA published a list of approved guns for SSP division like USPSA does for their Production division. That would make life for the competitor so much easier. Instead IDPA leaves the issue subject to the discretion of the Match Director.
Personalities become involved in the process as some MDs strive to look at things as legal unless specifically outlawed in the rules, while others seem to look at things as illegal until proven innocent. As an IDPA MD and Chief Safety Officer, I'm in the first camp - the gun is legal until
proven otherwise.

You mean like when I built up a S&W M&P 9c for the BUG division? Not in anticipation of a future rule, but per the then current rule. Even shot it in the BUG Nationals & legitimately classified EX with it. Then the rule changed, so last Spring I bought an M&P Shield 45 to serve as my "classifier gun". One single gun that I could use to maintain my required annual classification in all 5 semi-auto divisions. Rule change. Only good for 4 divisions now. Been there, done that. No T-shirts.

Yeah, I could do that. But, how does that look when the Match Director cheats by shooting a gun in SSP that's not SSP-legal?
