Guys,
I shot my S&W 3914 today that had the questionable (overpressure??) Silver Bear problem that started this thread. It worked fine digesting Walmart ammo perfectly and some other misc. rounds. I guess there was no permanent damage--I am happy about that.
I then shot up the last of my .45 LC ammo--I'm getting ready to migrate south in a few weeks. Good group, very satisfying.
Then I shot my 1936 Mauser Luger--wow. The sights are tiny and the trigger is heavy and gritty (compared to my good 1911s), but manageable after some tweaking based on a trigger article Hugh E-mailed me awhile back. The first 5 shot group (see the figure if John S. can figure how to post it) measured 1.5 inches, perfectly centered. Love that Walmart ammo. Eat your heart out Thor.

You bet Lugers are accurate if you can align the sights and squeeze the trigger carefully.
