Thanks for the pictures and posts.
You guys have "confirmed" my experience with these US/Texas/Mexico

made lugers.
They may have worked ok when new, but after some rounds, "things" begin to happen- all bad.
I believe all can be traced to use of the "wrong" stainless steel alloy.
Some of the "improvements" that Rich pointed out are similar to those used by Mauser in their 1970s luger revival, they made manufacture cheaper and quicker.
I can add that it is likely after some rounds that the safety lever loses its tension and will begin to apply itself after each shot.
Also the mag catch or notch in the magazine is in a slightly different place(vertically), so some or most original original magazines won't function correctly when trying to use in one of these reproductions.
I always "wanted" one, until I got one- then I couldn't get rid of it and its troubles fast enough.
