Hmmm.... I saw SilCo's 9K video and the numbers seemed high compared to other 9mm cans. That said, the thread you posted made a good point about this being a subgun can, with 70% of the volume of a full size 9mm can so I guess the numbers are pretty good. At an extra $100 or so over the Osprey it won't kill me but now the question is do I get the Osprey and leave the Ti-Rant on the MP or get the 9K for the MP and put the Ti-Rant back on the pistols? I've already invest in AAC's tri-lug though. So to get the 9K would be an extra $220-$240 over the Osprey.

I think the 9K would be right at home on the MP, and I'd get the Griffin 3-lug for it to keep the short length (cheaper too I believe). And the Tirant 3-lug is an excuse to do another PCC. But I honestly find switching between the Tirant 3 lug and the pistons to be a pretty quick process once it has cooled down.
