If anyone needed a reminder how significant Glock has become in the handgun world, consider we are at 23 pages in a thread on a .380. I can't remember any other thread here with a .380 as the main subject, and don't believe I have ever commented in a forum on a .380.
Glock has something BIG with the 42, arguably with even a higher buzz factor than if it was a small single stack 9mm. The only thing to be determined is whether it is big/good, as in becoming to .380 pistols what the Glock 17 is to 9mm service pistols, or big/bad as in a colossal failure that tarnishes the Glock brand. Assuming pistols are ready to ship, bet we know by summer.
