I just bought a Walther PPK/S, with a threaded barrel, a week or so ago for $270.00 on sale at Sportsman's Warehouse. Now it's not the Walther you think of James Bond carrying. Those were all steel guns, and go for about $800 (new) these days. The PPK/S in 22 is pretty much a plinker. The frame and slide are made of Zamak an alloy of aluminum and Zinc (and few other metals). So far it functions well, especially with CCI Stingers, or other ammo with some pop to it. It functions in S/A mode with any ammo I've tried in it, but fails to eject the round when fired in the D/A mode. I'm thinking this is going to get better as we shoot it and it get's broken in. If it doesn't it's not a big deal. We will shoot it in S/A 99% of the time anyway.
The double action trigger can best be described at "heavy." Which may actually be an understatement. The factory claims 17 pounds or so. It's at least that, but does have the advantage of at least being fairly smooth. The S/A isn't bad though, breaking at about 4.5 lbs average, with a nice clean break, and a nice reset. The sights are very small. Good enough for my plinking, but would probably need to be changed for use with a suppressor. The gun did come with two extra front sights, and a wrench to change them, as well as a wrench to remove the thread protector on the barrel. Not something I'll ever use, but it is there.
It seems to be a fairly accurate plinker for what it is, but I'm under no illusion that it will run with the Rugers, Smith and Wesson's and such. Oh mag capacity is 10 rounds. Extra mags are about $50.00 or so each.
Now this should give you an idea of why some 22's sell for at least twice what others do and for about the same as their centerfire cousins.
All we wanted was a "plinker" and my wife likes this little gun and darned if I haven't enjoyed shooting it, but it's not in the same class at all as a Ruger MK anything, Smith and Wesson Victory, or a Browning Buckmark. It's sort of a modern version of a H&R revolver.
And that is not a "bad" thing as long as you know what you're getting for the money.
One other thing. Normally they sell for abou)t $100.00 more. I just caught it on sale. I probably wouldn't have paid $389 (I think that was the "normal" price at Sportsman's Warehouse.) I'd have gone ahead and gotten a used Ruger.
