The rarer and more expensive P5C is identical except for length, which is 6.7" rather than 7.1" and 1 oz. of weight. It's hardly more compact as the butt and slide width are identical. Personally, I would rather have the extra velocity and site radius.
While the P5's owe an obvious lineage to the P-38, they are very different guns. It uses an enclosed slide and a passive firing pin block (the firing pin actually drops down out of the way of the hammer-very slick). The rear site has a screw for windage adjustment and dot over bar markings. The barrel is very heavy and is supported with extensions front and rear. Lock up is so tight it feels like a fixed barrel. There is no safety. The SIG style decocker is on the frame and also acts as a slide release. There is a smaller lever for manually locking open the slide. The mag release is on the heal, but is a push button rather than a lever-the mags go right into your hand for tactical reloads. The frame is aluminum and precisely machined with no marks. After several hundred rounds there is no finish wear on the slide rails. There are twin recoil springs that remain in the frame during normal disassembly.
The P5, like the P-38 and Beretta 92, uses a recoil system with a non-tilting barrel. All 3 weapons are known for consistant accuracy and unparalleled feed reliability. The extractor is the pop over type, rather than the rigid variety used in Browning set ups. It has been said the weapon will cycle without an extractor-haven't tested that one.
The P5, along with the Sig 225 (P6) and HK P7 PSP were designed to meet the strict specifications of the West German Police trials. It is the equal to the other two in design and function. Unlike the other two, there are no machining marks. Really beautiful production.
This is not a tiny gun. I'm selling an MK9 if you want that. This is the peak of perfection for a compact defensive arm, the kind of weapon that you would gladly trust your life to and really enjoy practicing with.
