I have an M40 and P99QA in .40.
My P99 has yet to malfunction in several hundred rounds, while my M40 will still have a sporadic malfunction.
The P99 has more muzzle flip as already stated.
I think, for now, you'll have more accessories for a P99 than any Steyr, but who knows, that may change in the future when Steyr is better established in the US.
Both guns are equally accurate.
I like the grip of the P99 a bit more than that of the M40, but I prefer the M40's trigger over that of the P99.
