Hi all. Bought a new M9-A1 about 3-4 weeks ago. Took it out after a thorough cleaning to try it out. I shot 50 rounds of WWB with several FTEs. Next, 50 rounds of Fiocchi, zero FTEs, 50 rounds or CCI with one FTE, and 50 more rounds of WWB with several more FTEs. After reading about the 1911 plunger spring trick on here, I tried it. Took it out today, and fired 100 rounds of WWB with zero problems at all. Now that it seems like it will be reliable, I'm not kicking myself for buying 4 extra mags before ever test-firing.
