This is quite an unusual weapon; designed in the late 70's, this was Walther's first foray away from the P38 style of handgun as duty weapon. It's full of strange design features and still has a little bit of P38 lineage in it. Click on each image to enlarge.
First, just a side shot.
Upon opening the slide, you can immediately tell that this isn't a browning-style lockup, the barrel stays linear to it's axis. I'll get to this.
The pistol has the classic European style magazine release on the butt behind the mag well.
One of the most unique features here is the articulated firing pin. Instead of a blocking style firing pin safety like you'd find on everything else, with the trigger at rest the firing pin is in a low position where the end finds a blind hole in the hammer and would not be struck if the hammer fell. When the trigger is pulled, the firing pin is pushed up where the hammer can strike it.
The takedown lever is at the front and simply unblocks the barrel assembly.
Here you see a little of the P38; the barrel is locked with a block, actuated by a pin that presses against the frame during recoil.
Barrel removed (inverted), locking block in the "unlock" position
And the last of the oddities, here are the dual small diameter recoil springs. This was probably done in the interests of keeping the pistol compact, avoiding the placement of the spring underneath the barrel of behind the grips (Beretta tip-up style).
The pistol has a very nice trigger and is probably very accurate, though I can't verify since it's not mine as its' for sale at the shop (price as yet unknown). Another little odd feature of the pistol is that the lever on the side is dual purpose (see photo #1). With the slide locked back, the first downward sweep on the lever will drop the slide forward. A second sweep will decock the pistol. If you need to lock the slide back with a loaded or removed magazine, you have to press upward on the upwardly-curved piece of metal on the frame ahead of the main operating lever.
So there you have it; the Walther P5 in a nutshell. Very strange gun :)
