Study Identifying Luger Caliber: .30 Luger or 9mm Luger?

lugerholsterrepair · 04-23-2017, 04:53 PM

Was there a specific time when the switch occurred from 7.65 x 21mm (.30 Luger) bottleneck cartridge to the 9 x 19mm Parabellum cartridge? Yes, almost immediately after George Luger invented it.

Was this transition across the board (did all manufacturers change simultaneously)? Yes, since there was only one manufacturer, DWM.

What was the reason for the change (i suspect it had to do with the forever argued concept of knockdown power)? Exactly! Good guess! There is little to argue about here really. BIGGER is better 100% of the time.
