Umarex Walther PPK/S

An extremely generous fellow surprised me with a Umarex Walther PPK/S BB pistol yesterday, just turned up in the mail. I emailed him and he replied that the slide kept popping off while firing and that he wasn’t able to get it back together. So he sent it to me as he knew I’d get it working and enjoy it. Sometimes airguns are like that, they drive you nuts until you just can’t stand the sight of a particular problem gun (I know I have several I’d like to run over with a steam roller).

As received.

The slide was detached. Googling around for information I came upon an excellent Youtube video detailing the disassembly and reassembly. Although I’m not a big fan of using a drill bit as a pin punch, but you do what you can with what you have.

Spring in place.

Unlike the pistol in the video, a previous owner had replaced the trigger guard with a laser sight made for the pistol. The pin that retains the stock trigger guard is not used. The trigger guard is pivoted down.

And twisted slightly to stop it against the frame.

Then the slide is slid on.

And down. It needed a bit of wiggling.

Part of the problem is that instead of using a pin to retain the trigger guard, thus locking the slide in place, the laser sight used two socket set screws. So I tightened those down. I think I’ll make small dimples in the frame to more securely lock them.

Looks cool…makes me want a “real” PPK.

Not a big fan of the bulky CO2 screw knob. But it does provide good leverage.

Four magazines loaded with steel bbs.

Inserting the magazine.

The gun felt stiff, and the plastic shroud around the barrel seemed tight. Several times when first shooting it the slide locked up, requiring manual recocking. I greased it up and it worked better but I’ll probably smooth it a bit.

The slot the CO2 cartridge fits in is pretty tight which makes replacing cartridges a pain. I think I’ll trim a little off the sides. You can see that it pinches the cartridge enough that it stands up…

It was getting late but I ran it a bit to test. The blue group is with steel bbs at about 10 feet. The red circles are a 5 shot group using lead bbs (not .177 lead round ball, will try that later) used in the Haenels.

The pistol isn’t particularly accurate and the laser needs to be zeroed to the point of impact (it was shooting low), as well I think it needs some gentle tuning. I’ll work on that later this week. It is a fun pistol, and while the “blowback” action serves absolutely no purpose, it looks and feels realistic.
