They were the same P-5 when the pics were taken, they are different P-5's now. I've pretty well dedicated the Uhl kit to the receiver of the non-import marked P-5. There is a small, round, urethane buffer that has to be inserted into the circular cutout at the rear of one of the recoil spring channels to provide additional tension on one of the recoil springs for the Uhl kit. This makes switching the kit back and forth on one frame a bit of a pain. So I now have a complete suppressed .22 P-5 and a suppressed 9mm P-5.
The P-5 9mm with the can shoots like a dream, nice and soft and quiet with 147 grain ammo. The Uhl kit is actually gas operated. A port in the bore just ahead of the chamber taps a small portion of gas into a cylinder where the gas pushes on a piston attached to the slide. The amount of gas tapped off can be adjusted via a set screw/valve on top of the barrel. The P-5 with Uhl kit is louder than, say, a Beretta 87 or PPK/S .22, but it is such a cool and unusual package, I can easily forgive a little extra sound.
