Just a little something to whet your appetite for the evening edition:

This one is definitely a case of "the good, the bad, and the ugly". I'm glad I glommed onto it though, since it may be years before I see one in stainless steel. And I'm definitely going to write Carl Walther (actually, Umarex), demanding that Kontrolle 16 be busted down to a 3.

Tonight's Saturday Night Gun Pron is a continuation of my work on the Walther PPK/S .22lr. Without tearing it down completely (some dire warnings in the owner's manual about going past ordinary field stripping), I was able to apply Nanolube to more parts, and exercise some functions manually.

I consider the weapon shootable now, if you have the hand strength of a gorilla. The DA pull is estimated at 30 pounds, since I don't have a trigger scale that goes that high. The SA pull is 8 pounds, at least 5 pounds heavier than it should be. We'll see how things improve once I start shooting it. Fortunately, I have plenty of .22lr, and I suspect it will take at least 200 rounds for break-in.

This is what can be expected from a gun wrapped in a plastic bag after the exterior was sprayed with cooking oil, and the innards were bone dry. Now it's clean on the outside, and reasonably well-lubricated on the inside.

Risking voiding the warranty, I removed the grips for a better look inside while I field-stripped the handgun. From photos of Umarex's PPK/S airsoft gun, both start out with the same basic frame, which is some sort of heavy non-ferrous metal, and then made into their respective forms. Top priority is to assure that an airsoft gun can never be converted to fire live ammo.

The inside of the slide shows the airsoft construction method of stacking small flat parts together, and holding them with screws and nuts. That can give you a complex shape, although it has more potential for trouble than a slide milled out of solid steel. Along with airsoft guns, these replicas are designed around the principle that a milling machine (which needs a skilled operator, even if it's CNC) is verboten in making these things. The mechanism in the frame bears a slight resemblance to a real PPK, except many of the components are molded pressed metal, rather than machined steel. A "manhole cover" near the hammer is removable for access to more of the mechanism. Finally, the rounded center area in the grip is cut out for the airsoft frame, because the pressure cylinder goes there. Unfortunately, this means both versions use hollow ultra-thin grip panels, which makes it almost impossible to put some fancy wood grips on.

Most people will not notice the removable tension-barrel system, which has real advantages in providing consistent barrel rigidity, comparable to a big, fat target barrel. Target barrels were/are big and fat to provide more rigidity, and hence more consistency. Tension barrels allow you to do the same thing, with a much lighter construction. Plus, the end cap that pulls the barrel forward to provide the tension, can be replaced with a $10 threaded version that puts the threaded adapter for a suppressor in front of the slide.

So that's about all I know about the PPK/S right now. Looking at Walther's ads and images, I suspect the stainless steel version has been photoshopped to make it look more shiny and polished than it actually will be. I find this modern "service finish" to be acceptable, although it is nothing as handsome as the fit and finish of the real PPK with its hand-polishing and slow-rust blue color. The only cosmetic machining are the flats on the slide, which were probably given a quick trip through a surface grinder for a semi-gloss brush-finish treatment.

So I was back at the store today, where they just put out the IWI/Umarex "micro Uzi" .22lr pistol. They were making up their little info cards that a placed next to the guns in the display case, when I told them I'd take the PPK/S without them bothering to unpack it.

I don't know what's happening at Umarex, but the micro-Uzi had "issues" too, mainly because nobody studied it before it went into the case.

The cocking handle on top would not retract the bolt, and the sales guy admitted he didn't know how to take it down to have a look. I popped off the slide cover (it helps to be familiar with real Uzis), and while the bolt was fully forward, as a closed-bolt weapon should be, nothing I tried could help me pull it back into the position needed to feed another round from the magazine. However, I did notice it was bone-dry inside, just like the PPK/S. Since I didn't own the gun, and now wouldn't buy one on a bet, I agreed with Sales Guy that the micro Uzi could wait until Monday for their gunsmith to ponder the situation. I assume it's something simple, but I hope the buyer doesn't have to settle for a 30-pound trigger pull to have a working plinker. Until I learn more, and see how my debugging proceeds, these two items are both in the caveat emptor category. :)
