blkbrd666, you did well. I'm a big fan of the Walther, too. I have a brace of P-1s, a downstairs gun and upstairs. I can't tell from the pix, but do yours have the reinforcing rod between the takedown latch and the trigger? I've heard it helps the durability, but neither of mine are so equipped. I'm not worried about the lack, but I know on some forums, people recommend the rod for extremely heavy duty.
I'm actively thinking about buying a third P-1 and having my friendly smith cut the barrel and dovetail a hi-viz front sight in the slide. An instant P-38k, or was it the P-4? Except for the width across the dual recoil springs and muzzle blast from the short barrel, it would make a neat carry piece.
My experience with the P-6 is non-existent. However, I had a friend in the early 80s who bought a BDA in 9mm. That was the Browning import of the SIG and probably wasn't much different from the -6. Nice gun. Fun to shoot and accurate.
Enjoy your new friends.
