I have been casually looking for a P99c AS .40 too. It would complete my set, I have P99 9mm and .40 as well as P99c 9mm, all AS.
I don't really notice that the recoil is much more with my fullsize .40 than my fullsize 9mm. (Unless I practice shooting single handed, with my left "off" hand.)
But then again, when I first got my P99c, I didn't really care to shoot it with +P loads after shooting cheapo plinking loads. But now it doesn't seem to matter.
Anyways... I've bought my 2 handguns for the year, even though I try to limit myself to one/year.
