I posted extensively here in the archives about my S&W PPK/S. Before, during, and after the recall. There should be a dimple on top of the tang behind the hammer, as you look down at the top of the pistol, hammer down, tiny little machine mark should be present.
I do not know if the one's made since the recall have the mark, as they should be correct coming out of the Houlton, Maine facility.
Easily checked at the S&W website. via serial number.
They love lube!!!!, A moderate break-in is recommended at the Walther forums, and from personal exp., as the gun is made to very tight tolerances.
The de-cocker needs to be lubed and flipped back and forth about 27,987 times,...(just kidding), but they do loosen up.
Never had a FTFire, but I have never shot that type of ammo. Usually, the "cheapest" I'll go is Aguila .380... and it shoots it fine.
Magtech, Georgia Arms, CCI, all work fine, for target ammo, and I carry Speer Gold Dot, or Cor-Bon DPX for carry, (also in my Kel-Tec),
Really get in there and lube everything, pull the grips off and get in there too, also the factory mags are probably bone dry and a TINY bit of lube really helps as well.
After I got mine back from the recall it was sent back dirty, (I sent it clean), and it had NO Lube at all. But they test fired it at the plant, (which is good), . Let me know how it works out, it should be top notch with another brand of ammo.
Even after breaking in, it might even fire that other stuff, but I'm not familiar with it..
