Wow, great info, thanks, guys - you really know your stuff
Yes, I figured out the part about the magazine not matching. It is kind of ill-fitting, has the aluminum botton, and no serial number. Apparently having a matching mag is a rare thing anyway.
Even though the finish may not be perfect, I am pleased with the very nice mechanical condition of the pistol. It definitely does not look its age.
I am looking forward to taking it to the range this weekend.
Question: I think I will replace the grips and get a couple of new magazines for it.
Any recommendations?
