I did like the PS90's recoil characteristics. If they could reproduce that feel with a larger caliber all the better.
I didn't like:
The plastic shroud around the barrel
The way you held it
The sight from the factory(although interesting and had potential)
The price of AMMO jesus
I didn't like what the ammo did balisticly(the civilian stuff)
Some guy made a good point "Its the coolest 22 magnum ever"
