G.T. thought this might be of general interest, hence this post...
Long story short:
I currently have 5 mags for my Luger: an Erfurt from the teens, an "older" Mec-Gar; and three (3) Triple-kays, each (of the latter) with a G.T. installed FXO spring.
The Erfurt and older Mec-Gar work pretty well most of the time, although every once in a while the Mec-Gar won't hold back, and the Erfurt won't feed its last round consistently. G.T. was able to improve them substantially (no more stovepiping or jams, but they continue to give the occasional holdback/last round problem - not enough to worry about. MAY or may not be ammo related.
All 3 of the Triple-kays have been working flawlessly. They only hold 7 rounds instead of 8, but its starting to look like these are the hidden gems.
Continued research at the range is indicated!
