Scott - My grandfather left me one when he passed on. One he brought home from the war ( WWII ). It still has the Nazi insignia on the frame. I think it's a P-38, but I can't say for sure. I will pull it out and inspect it this weekend, post some intel on it for you.
One thing I know for sure is that the mag release is on the bottom of the pistol grip, like the Ruger's. I always considered that a drawback personally, but I don't know how anyone else felt about it.
I remember that the mags were steel, and the spring, even after all those years, was strong as, well - it was really strong.
I remember the slide to frame fit was pretty good actually, not much rattle at all.
Now I got myself wondering. Let me see if I can't dig that out this weekend take a couple pictures for you...
