I have an SW99 (Pre-agreement).
It loves CCI, Lawman, Magtech...
It does not care too much for PMP 115 grain FMJ. The PMP had very light felt recoil, it barely cycled (the weapon never jammed).
I had bought several boxes of S&B and it would not work in my M40 at all. Gave it to my friend who brought his P99 in .40 and it had not a problem. I love the looks of the P 99 but can't get used to the decocker position and the mag release.
Fed AE, Win USA, Rem UMC, Speer Blazer and Lawman, PMC all worked. Blazer was the dirtiest, Fed the cleanest and fastest (115/1160 as advertised, Glock 17), PMC the cheapest and slowest.
