Yeah, the P-06 and the all steel Compact, both in .40 S&W, went out of production about that time as well.
Actually, I think if CZ had offered these pistols in .357 SIG, they'd have sold A LOT more than they did in .40 S&W.
At near .357 Magnum power, the .357 SIG is much preferable to the .40 and doesn't kick all that much more than a +P 9mm load (IMO).
