I really like the concept of the PS90, only thing keeping me from buying it is the price. I hate buying anything I can't get the cost out of, wether I plan on selling it or not. The 5.7 cartridge is weak sauce in comparison to 5.56, but what platform offers 50 round standard mags in a platform that small and handy? Besides, no one complained about the energy/performance of the 17 hmr when it came out. As far as the standard sights go, agreed they are pretty weak, which is why you should get the tri rail and put on what you like.
The 17 HMR is intended for squirrels and gophers. No one sells it for self-defense. I would rate it a good SD round if zombie squirrels are a worry. Step up to the 5.7x28mm and zombie groundhogs should be in danger.
The comment about caliber adaptability on the XCR and ACR is good, but XCR caliber conversion kits run something like $500, not far from just buying a new AR (and as much or more than a new AR upper with barrel). I like the looks of both of them, but they will be (ACR) or are (XCR) pricier than the AR options that you can buy today.
