So I recently acquired this 1970 P64 from a buddy who doesn't understand anything mechanical. He sold it to me because it didn't work. Basically long story short, firing pin spring was broken and the hammer spring was a bit stiff.

So $12.00 in parts and $100.00 for the gun. I say good deal for me.
Took it out shooting after fixing it up and was impressed. Doesn't shoot as well as my 1858 Remington's, but then again I can't carry them in my pocket.
Here are some pictures. Enjoy
